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

  • #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
