- Changes from v5.3
- Improvements: 3
- Specification changes: 7
- Bug fixes: 15
Improvements¶
- #141 Prepare FLOPS values
- #425 Add test samples for contact analysis
- #459 Efficiency improvement of hecmw_mat_con
Specification Changes¶
- Code reorganization (refactoring) of the Lagrange multiplier method contact analysis
- #101 Define the Lagrange multiplier matrix with HEC-MW
- #421 Always use conMAT for the matrix structure of contact analysis
- #422 Refactoring of fstr_matrix_con_contact

- #424 Refactoring of the solve_LINEQ_contact series solvers on the FrontISTR side
- #316 Remove Document(Manual)-CI from FrontISTR's gitlab-ci.
- #438 Reorganization of cmake_minimum_required
Bug Fixes¶
- #205 The mises stress is not output in the layer-wise result output of shell elements
- #338 Terminates with an error if a coordinate value contains a floating-point number with only 1 significant digit in the mantissa
- #371 Occurrence of division by zero in certain development environments
- #378 Defect in the restart I/O of dynamic analysis with SURF-SURF contact
- #381 Problem that tutorial 04_hyperelastic_spring does not converge
- #397 Reading error of the temperature (2 or more temperatures) dependent property values of the creep Norton law
- #409 SIGSEGV during the partitioning of a contact model
- #411 [bug] Regarding the contact analysis function in parallel computation (continuation of inquiry 1220302050) (1562686629)
- #427 Fails in the domain partitioning of a model with contact
- #428 Error when there exists a Rank whose host name is longer than that of Rank 0
- #429 When using the MPC constraints of the Lagrange multiplier method and the degree-of-freedom elimination method together in parallel analysis, the matrix size change processing of each (hecmw_mpc_mat_ass, etc.) is inconsistent, and the analysis fails
- #439 In the multi-step analysis of transient heat conduction analysis, the progression of totaltime is abnormal
- #457 Defect in the name resolution of contact pairs
- #458 In hecmw_solver_las_22, 2_R must be called instead of hecmw_update_3_R
- #460 The internal direct method and DIRECTmkl cannot be used in serial contact analysis
