L2 norm of Residual forces overflowing error

      Hello everyone, 

      I am performing a non linear structural analysis in ANSYS workbench 19.1 on my university licenses and I received the following error:

       *** ERROR ***                           CP =    1868.234   TIME= 14:34:55
       The L-2 norm of the residual force overflowed.  This may be caused by  
       PRED,ON or birth/dead elements.  Please use PRED,OFF and try again.    

       

      R E S T A R T   I N F O R M A T I O N

       REASON FOR TERMINATION. . . . . . . . . .DOF LIMIT EXCEEDED                     
       RESTART BY RE-RUNNING THE ANALYSIS

       ALL CURRENT ANSYS DATA WRITTEN TO FILE NAME= file.db
        FOR POSSIBLE RESUME FROM THIS POINT

       

       

      I even entered the command suggested but still the simulation did not work. Since I am using a commercial license there should not be an issue of the number of elements as well which was suggested in one of the older posts.Thanks in advance for your help.

       

       

       

      Kind Regards

        Hi Ashish

        I tried the following the steps suggest in the link but even then I am getting the same error. 

        I even tried using the birth/dead element commands but as soon as the second load step starts, I get the same error. 

        How should I proceed. 

        Kind Regards
