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
Diverged 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              = _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
