Hi Helen,

Just to close the loop. If you do try to change the nonlinear option, such as one plasticity model to another you will get this type of error.

 *** FATAL ***                           CP =     191.328   TIME= 14:33:48
 Change a nonlinear material model, 2, to another nonlinear material    
 model, 1, is not allowed for element type 186.                     

 

 

Regards,

Sean
