Hello Team,

I am struggling with error (mentioned below) from the ANSYS Modal run for full vehicle frame model:

*** ERROR ***     SUPPRESSED MESSAGE    CP =     361.113   TIME= 12:08:58
A large negative pivot value ( -7.647801779E-03 ) has been encountered  
in the global assembled matrix at the UZ degree of freedom of node      
1418289.  This may be caused by a bad temperature-dependent material    
property used in the model.

 

Everytime the node number (in this case: 1418289) will be different (anywhere in the model) from modal runs.

Which checks I am supposed to do in my hypermesh model to avoid such error?

Please help me to resolve this error.
