This DEFORM v10.2 release includes 1. 2. 3. 4. 5. DEFORM-2D v10.2, DEFORM-3D v10.2 DEFORM-F2 v10.2, DEFORM-F3 v10.2 DEFORM-F23 v10.2, Integrated-2D3D v10.2 Integrated-2D3D v11.0 (beta, on PC only) DEFORM License Manager v3.0.3
DEFORM v10.2 comes with an updated License Manager 3.0.3. To run DEFORM v10.2 and DEFORM v11.0(beta), the minimum required version of the License Manager is 3.0.2 This version of DEFORM v10.2 requires a password for v10.2. DEFORM v11.0(beta) included in this release can also run using the DEFORM v10.2 password. Due to the major enhancements in DB structure to include new features and functional improvements resulting from several ongoing developments, database structure in version11 is not compatible with v10.2. V10.2 system can not process or run v11.0 database. Although v10.2 can be run in v11.0 by creating the required –ve step in v11.0 pre-processor, it is generally not recommended to mix different versions in the same database. A database conversion facility (from 10.2 to 11) will be provided when the DB structure in v11 is finalized.. Details on the license manager version, product version and password compatibility details are given at the end of this document. DEFORM v10.2 GUI related updates 1. (2d v10.2) Sliding die definition between rigid objects can now handle inter-object relations for non-consecutive object numbers. Geometry points of the slave die must see a master geometry segment for the rigid die contact to be active. This reported issue was in DEFORM v10.1, where the rigid dies were seen to penetrate each other even with a master-slave relationship defined. 2. (3d v10.2) 3D geometry import now allows the file name extensions for .PDA and .PAT formats. The reported issue was in DEFORM v10.1, where geometry files with only .PDA extension were allowed. 3. (3d v10.2) A stability issue related to handling point-tracking points when the object splits into two has been addressed. The reported issue was in Linux version of DEFORM v10.1, where the system failed to locate the new position of the tracked point on the split object.

4. (3d v10.2) An issue related to path movement definition in local frame has been addressed. The reported issue was in DEFORM v10.1, where path movement was defined in local frame as a function of time. 5. (3d v10.2) A vector plot display issue has been addressed that occurred when the display had been zoomed and animations were saved. The reported issue was in DEFORM v10.1, where the vector display was set on a sliced plane, and user saved animation in a zoom window, the vector size was not properly scaled to the new window setting. 6. (3d v10.2) The issue has been addressed relating to saving the strain scaling data between the rolling passes when user opens, saves and closes the project file. The reported issue was in the Shape Rolling module of DEFORM v10.1, where the user visited a project file and saved the master and project files, the strain scaling information was not correctly saved. 7. (2d3d v10.2) Capturing work space image and capture image to clipboard issues have been addressed. The reported issues were in DEFORM v10.1, where users were required to avoid the use of ‘Aero theme’ in Vista and had to opt for ‘Window 7 basic’ on Win7 PC operating systems. 8. (3d v10.2) Local and global time are now correctly handled in MO2 and MO3 modules when operation cycles are used. The reported issue was in DEFORM v10.1, where global time after each operation was getting set to zero when operation cycles were used. 9. (3d v10.2) Velocity and symmetry boundary conditions are now retained for multi pass ALE shape rolling symmetric models. The reported issue was in the shape rolling module of DEFORM v10.1, where the velocity boundary conditions at the beginning and end surface of the workpiece and the symmetry conditions were getting mixed up when run time data was generated from one pass to the next. 10. (3d v10.2) Improved data checking when sliding die definition is used in the shape rolling models. The reported issue was in DEFORM v10.1, where sliding die movement data was defined on a symmetric model with one roll and workpiece. The data checking was blocking the database generation indicating insufficient movement data. 11. (3d v10.2) An issue related to extracting coating mesh information has been addressed. The reported issue was in DEFORM v10.1, where a model keyword file was loaded into the preprocessor (with coating mesh and coating materials defined) and the coating mesh information was not correctly extracted from the loaded file.

12. (3d v10.2) Inconsistency between 2D and 3D has been addressed dealing with plotting principal stress summary graphs. In DEFORM v10.2, when min/max summary plot on principal stress is requested in the post processor, the plot contains two curves that include minimum of minimum principal stress (Sig3) and maximum of maximum pricipal stress (Sig1). Issue was reported in DEFORM v10.1, where both of the curves plotted maximum principal stress. (i.e min/Sig1 and max/Sig1). DEFORM F2, F3, F23 related updates 1. (F2, F23 v10.2) An issue has been addressed dealing with the wrong unit system being displayed in load-stroke graphs. This bug was reported in DEFORM v10.1. 2. (F2, F3, F23 v10.2) Consistency issues were addressed in handling the operation type while adding additional operations to an existing project or database. The reported issue was in DEFORM v10.1, when the first operation was set up by loading a database of a hot forming operation, subsequently added operations were not retaining the hot forming settings correctly. 3. (F23 v10.2) A bug has been addressed relating to keeping the mesh hidden while flownet and state variable are displayed for several steps. The issue was reported in DEFORM v10.1, where the hidden mesh turned back on when the step was changed. 4. (F3 v10.2) The handling of the positioning dialogs was improved when object geometry is imported. The issue was reported in DEFORM v10.1, where the object positioning options were not available for the imported object geometry. 5. (F2, F3, F23 v10.2) Force interpolation procedures were improved and now do not require users to specify any tolerance values for force interpolation for die stress analysis. The system now adaptively computes the tolerance value to achieve optimal force balance between the workpiece and dies. 6. (F23 v10.2) An issue related to maintaining the vector size when displaying vector plots across the steps has been addressed. The reported issue was in DEFORM v10.1, where the size of the vector was not properly maintained during the animations and on section plots. 7. (F23 v10.2) The handling of local and global viewport information was improved. Local viewport settings are now maintained in the current session, while the global settings are maintained across the sessions. This issue was reported in DEFORM v10.1, indicating the loss of local viewport

settings once the user switches from one project to the next in the current session. DEFORM v10.2 FEM related updates 1. (3d v10.2) A memory leak has been addressed that was found in the DEFORM v10.1 64 bit FEM engine in MPI mode on Linux operating systems. 2. (3d v10.2) On both PC and Linux, a consolidated 3D FEM engine has been implemented. The Task Manager will now only display multiple MPI instances of DEF_SIM.EXE, instead of either DEF_SIM.EXE, DEF_SIM_P4.EXE or DEF_SIM_P4P.EXE depending on the MPI setting. 3. (3d v10.2) Semaphore cleanup procedures on Linux operating systems have been further improved in DEFORM v10.2. More checks and cleanup procedures have been added to the command scripts used in running the model. DEFORM v10.1 had some reported issues of left over semaphores causing failure of MPI jobs. This reported issue was more pronounced in cluster environments. 4. (3d v10.2) The text-based data extraction module on Linux (DATEXT3.EXE) has been updated to handle database structure changes. The reported issue was in DEFORM v10.1.1, effecting users running their own automatic text-based procedures to process results from multiple DB files without visiting GUI modules. 5. (3d v10.2) An issue has been addressed dealing with increasing element strain values in the rigid zones while using nodal strain definition. This issue was reported in DEFORM v10.1. 6. (2d, 3d v10.2) A bug was fixed in handling the die velocity and state variable updating for plastic objects while the press is stretching due to low stiffness. A message will now be flashed accordingly when the resulting die velocity is approaching zero (due to press stretch). Inconsistencies due to resulting energy computations were also addressed. In DEFORM v10.1, the reported issue was that even though the die velocity was zero, state variables were seen to accumulate. 7. (2d,3d v10.2) Handling of state variable updating was improved for plastic objects under low press stiffness and large press. This update also accounts for more accurate energy and die load predictions. Issues reported in DEFORM v10.1 included 1) state variable change while the press was stretching without any workpiece deformation, and 2) an inconsistency between the energy computations based on the die velocity and load compared to that of post processor computations.

8. (2d, 3d v10.2) A bug was fixed in handling the grain recrystallization kinetics based on average deforming strain rate and critical strain rate. This DEFORM v10.2 fix ensures that when the deforming strain rate is above the critical strain rate, material points undergo metadynamic recrystallization correctly. Examples to illustrate this feature are included under the HeatTreatment folder in DATA folder. 9. (2d, 3d v10.2) A bug was fixed in handling the material diffusion coefficient when models 3 or 4 were used (i.e D=C1(T)exp[C2(T)A] or D=C1(A)exp[C2(A)T] ). Issue was reported from internal testing for DEFORM v10.1.2+, where it was found that the function data handling for the coefficients C1 and C2 in these two models was not correctly handled. 10. (3d v10.2) In DEFORM v10.1 version, there was a user report indicating difference in model thermal response compared to 3d v6.0 with tet mesh models. The following is a discussion of this issue. In 2002 (3d v3.1.2), a special technique was introduced to minimize the effects of tet mesh topology on thermal behavior. This remained as the default setting until version 3dv6.0. Starting in 3d v6.1, based on user complaints and further internal testing, this setting was made conditional to exclude the models with internal deformation heat or heat flux boundary conditions. Users can override these settings using the control file TSMOOTH.DAT in the working folder. This would turn off thermal smoothing on tet mesh models. When the first line in the DAT file is ‘2’ smoothing will be turned on. From 3d v6.1, an additional facility was added to enable thermal contact when a single slave node comes in to contact with master segment. To turn off this feature user can place TSGLCNT_OFF.DAT in the working directory. 11. (3d v10.2) Improvements were used in handling the penalty number when symmetry plane boundary conditions were used. The reported issue was in DEFORM v10.1, where under specific conditions (large objects with coarse elements and symmetry velocity boundary conditions defined) bias in the deformation stress field was observed. In DEFORM v10.2, this issue has been addressed by adopting a consistent penalty approach for handling both the velocity and symmetry boundary conditions. More studies and improvements are underway to make this penalty number handling fully adaptive. 12. (3d v10.2) Issues have been addressed related to mean stress computations for 3d elastoplastic models. The reported issue was in DEFORM v10.1, when nodal stress definition was used, mean stress predictions were wrong in spring back models following forging. Using DEFORM v10.1, the only work around for this issue was to use element stress definitions instead of nodal definitions.

13. (3d v10.2) Issue has been resolved dealing with stress computations when a model has multiple elastoplastic objects. The reported issue existed in DEFORM v10.0 and v10.1, and the problem was caused by a fundamental change in the element local number handling done in DEFORM 3Dv6.1. 14. (3d v10.2) Issue in handling deformation step size defined as a function of stroke across remesh steps has been addressed. The reported issue existed up to v10.1.2, in which the step size used for the first step after remesh was wrong. This has been addressed in DEFORM v10.2. 15. (3d v10.2) Issue related to rotational axis update for objects defined with translation and rotational movements has been addressed. The reported issue was observed in v10.1.2, where in position of rotational axis was not updated for additional translation when defined for the same object. 16. (2d v10.2) Issue in updating the stress components for elastic plane stress models has been resolved. The reported issue was observed in DEFORM v10.1.2 and was caused by code changes were implemented into DEFORM v10.1.2 to compute elastic sintering shrinkage. 17. (2d v10.2) 2D FEM engine can now handle induction heating models with dual frequency input data for current frequency. For 3D FEM engine the corresponding functionality is available in v11.0(beta). Example models are provided in the Induction Heating sub folder of DATA folder.

DEFORM v11.0(beta) updates (for PC only) 1. (3dv11.0 beta) Updated version of Next Generation Post processor. 2. (3d v11.0 beta) Resistance heating functionality has now been implemented in DEFORM v11.0. This functionality is now available for both brick and tet mesh models. New examples have been added to the DATA folder.
3. (3d v11.0 beta) New options are provided in computing nodal pressure. Considering the orientation of the polygons in contact with the die and the contact conditions, this version allows users to compute both upper ans lower bounds on the pressure computations in post processor.

4. (3d v11.0 beta) Mesoscale modeling capabilities have been developed in the DEFORM system to model the behavior of microstructure evolution. For given initial nodal microstructural parameters and defined recrystallization kinetics, evolving parameters such as grain size, number of grains, dislocation density and resulting instantaneous flow stress can be computed using this functionality. (Material data: Grain)
5. (3d v11.0 beta) System improvements have been made to model the extrusion process. These improvements include an improved FEM engine and an updated template to generate the model details required to carry on the extrusion computations. This functionality is undergoing continuous improvement and updates will continue to be available.

6. (3d v11.0 beta) An improved Ring Rolling system is provided to setup the initial the model with deformation history from the previous operation. This improvement allows users to import a 2D model with deformation and thermal history and setup a 3d ring rolling process model.
7. (3d v11.0 beta) New D3D system (Digital 3 Dimensional Micro Structure), that allows multi-dimensional damage modeling capability (model #11) has been implemented. Within one damage model user can define initial data and evolution of micro void size, number of micro voids, fraction of coalescence and total porosity at the element level using this new micro void damage model. This model is designed to operate on six pre-defined key files representing current specimen structure and is designed to handle only the crack opening mode. (C:\Install_path\v11.0_Beta\DEF_GUI_D3D.exe) 8. (2d v11.0 beta) Torsional elastoplastic modeling capability has been implemented. Up to DEFORM v10.2, this was only available for rigid plastic models. 9. (2d v11.0 beta) Interface heat transfer coefficient handling from advanced BCC has a reported issue in 2d v10.1.2, making it non functional when advanced BCC is defined on multiple boundary segments. This issue has been addressed in 2d v11.0 beta.

10. (2d3d v11.0 beta) An integrated machining distortion module has been implemented. The user needs to select either 2d mode or 3d mode to start with and this product has no 2d3d converter yet. This new system can handle multiple operations and multiple passes within each operation. This module can read existing 2d machining distortion project files while in 2d mode. More features have been added with respect to boundary conditions, including pressure and distortion free boundary conditions. 11. (2d3d v11.0 beta) An improved 3D geometry tool now has basic morphing techniques which adds great design flexibility for parametric model design. Geometry morphing allows one primitive geometry to change into another through interpolation. Morphing can also work on design features with user-defined weighting parameters to guide the shape evolution within the constraints imposed on the geometric features. DEFORM License Manager 3.0.3 updates The License server v3.0.3 released with DEFORM v10.2 now records service termination details in the session log file indicating which client has restarted the License server. Typical location of this log file is On PC C:\Program Files\SFTC\License Manager\log\yyyy\LMmmddyyyy.log On Linux /usr/local/SFTC/LicenseManager/log/yyyy/LMmmddyyyy.log (mmddyyyy being the month,day and year format) For example to see license log for April 24th 2011, look for the details in ….. /log/2011/LM04242011.log

System related notes: 1. (2d3d v10.2) Actively running DEFORM jobs now do not allow the system to go into sleep/standby mode regardless of the system settings. The reported issue was in DEFORM v10.1 and v10.0 on PC operating systems where long running jobs were facing runtime and license issues when the system went into standby mode due to long idle time at the keyboard. 2. On PC operating systems (XP, Vista and Win7), it is required that the user installs Microsoft Visual C++ 2008 SP1 Redistributable Package (x86) and Power Point 2007 to be able to generate PPT file animations from within the DEFORM system. 3. Issue related to importing DEFORM generated .wmv file into a PowerPoint file has been addressed. This fix is now verified for PowerPoint 2003(PC), PowerPoint 2010(PC) and PowerPoint 2011(Mac). 4. User routine support is discontinued for Absoftf90 versions v7.0 and v7.5 5. For both 2D and 3D user routine support now includes Absoftf90 v9.0 and v11.0. Corresponding object files, build scripts and batch files are available in the product installation folders (\UserRoutine\DEF_SIM under 2D and 3D paths). 64 bit user routine support for PC is only available with Absoftf90 v11.0. 6. On Linux operating systems, 64 bit FEM support is available only for Centos 4+, Centos5+ and Suse Enterprise Linux Desktop (Suse11) operating systems. 7. Batch Queue and simulation server related Issues reported on Linux operating systems, have been addressed in DEFORM v10.2. Issue was reported in DEFORM v10.1 where in, it was observed that batch job submission faces significant delay even though license is available. 8. For the multi processor environments on PC compared the previous release, there is no change of Mpich versions used in DEFORM v10.2. Unless these are installed with earlier versions it is now mandatory to install 32 bit Mpich1 v1.2.1 for 32bit machines and additional 64 bit Mpich2 v1.2.1 for 64 bit machines. 9. This version also includes a beta version for DEFORM v11.0, which will continue to evolve with new features and is available only on PC. This DEFORM v11.0 version comes with only integrated version and the modules in which feature enhancements are being made.

10. From DEFORM v11.0, there is a significant change in the database structure to handle new developments and features. The Database generated with DEFORM v11.0 is not compatible with DEFORM v10.2. User should not do partial runs of a single model with these two DEFORM versions. 11. System documentation for DEFORM v11.0 beta is not available for this release. This will be available with official v11.0 release. New features and latest developments will continue to become available in this v11.0 beta version.
