- Improvements: 8
- Specification changes: 2
- Bug fixes: 10
- Others: 1
Changes from the Previous Version¶
Improvements
- Improvement of the contact analysis function: search speedup, refinement support, and many other bug fixes included
- Output of element principal strain / principal stress
- Added the –t option for specifying the openMP parallelism count
- Added global variable output to the result file: time, eigenvalues, etc.
- Mass matrix computation for shell elements
- Added the explicit method for dynamic contact
- !INITIAL specification in the analysis control file
- intel MKL pardiso direct method solver I/F support for non-contact analysis and distributed parallel
Changes from the Previous Version¶
Specification changes
- Change of the load amount of Tutorial 01 (deformation too large for linear analysis)
- Moved the follower force update timing in the Lagrange multiplier method contact from the beginning of the substep to inside the NR iteration (unification of the specification with the NR method without contact)
Changes from the Previous Version¶
Bug fixes
- Uninitialized variables in the implicit method for dynamic analysis
- Memory leak in the SSOR preconditioner
- Segmentation fault in fstr_make_dynamic_result
- Problem that some test examples fail
- Automatic time incrementing of heat conduction analysis
- openmp parallel support for heat conduction analysis
- Leak of memory release in the iterative method preconditioner
- Unnecessary call of ML_Set_Symmetrize in the AMG preconditioner (ML package)
- Problem that !SUBDIR is not thread-safe
- Problem that mixed computation of 33 shell and 33 beam cannot be done
