Hello. I'm trying to recreate simulation setup for further changes but I cannot get convergence on recreated setup. I am doing same setup but divergence occurs. So i compare logs and there is only one different line in log.
Converged solution: Code:
DELETE RESTART FILES OF ENDSTEP **************************************************** ******************* SOLVE FOR LS 1 **************** PRINTOUT RESUMED BY /GOP SELECT FOR ITEM=TYPE COMPONENT= IN RANGE 9 TO 9 STEP 1 1 ELEMENTS (OF 8810 DEFINED) SELECTED BY ESEL COMMAND. APPLIED BOUNDARY CONDITIONS OR FORCES FOR JOINT ELEMENTS SPECIFIED VALUE FOR SELECTED ELEMENT ELEMENT NUMBER = 0 LINEAR OR ANGULAR VELOCITY LABEL = OMGZ SET ACCORDING TO TABLE PARAMETER = _LOADVARI152 Code:

APPLIED BOUNDARY CONDITIONS OR FORCES FOR JOINT ELEMENTS SPECIFIED VALUE FOR SELECTED ELEMENT ELEMENT NUMBER = 0 LINEAR OR ANGULAR VELOCITY LABEL = OMGZ SET ACCORDING TO TABLE PARAMETER = _LOADVARI70 The only difference in settings is that geometry is imported in workbench from first structural analysis to second structural analysis. What is _LOADVARI70 /_LOADVARI152 ? Can I change something to make both simulation converged? Regards, Oskar |
