Is there a way to handle solver warnings like "zero pivot" problems?

Hello everyone,

 

is there any way to decode solver warnings? I want to know, in which part of the geometry (node/element) the problem is exactly.

For example a warning/message could be like this:

PCGLSS0204:Negative or zero pivot -3.490117e+000 at row 7284r)  

 

Or can I have a look into the result-files or log-files to get an idea, where the problem is exactly?

Up to now I can only do random changes to the meth or the constraints until the simulation works without problems. It would be great to get some ideas what to change to save time iterating.

 

Best regards
