Assigning crystal plasticity material constants for one crystal with more than one element (default of Dr Huangs model)

Hi!

 

I am just a beginner in Abaqus UMAT and I have started working with Dr Huang's crystal plasticity UMAT in Abaqus.

When I am assigning one material constants for one element crystal it works but when I try to assign it to more than one element for one crystal (for example group of elements with same grain orientation) it give me error code 144.

Can anybody explain me the reason?

 

 

Thanks in advance,

Kind regards,

Omid

I tried assigning one different material constants for each element (by defining different material constant and section for each element) using a orphan mesh but still it gives me the same error.
