I'm having problems with a model I'm testing. I get the error zero shear modulus at element "0". I have looked for this error in the forum, but only I found this thread:

I attach my script. Thanks.

Hi,

It seems there is a very small region in your model where material has not been assigned. To verify this, you can use the "Apply All" option to assign a single material to all elements. After doing so, solving the model should proceed without any issues.

My guess is that you imported a DXF file containing a tiny, nearly invisible area that was not properly closed. I recommend cleaning up the model to ensure all regions are closed and then assigning materials accordingly.
