UMAT subroutine development

UMAT subroutine development

UMAT subroutine development

(OP)
Hello

I have written a UMAT subroutine but when i run the code it runs and completes successfully. I am using C3D10H elements and FUNG model. The subroutine is working fine, as the job completes successfully. However, when I try to see the results from the ODB file I get the following message error:

“The selected Primary Variable is not available in the current frame for any elements in the current display group.”

Could this be because there is something wrong in my subroutine? I will appritiate your input. Please see the data file attached.
Could you please try to assist.
Thank you.

I have tried to select the stress, strain and magnitude and all not available. This is not realistic as this should be available. Do you think my Abaqus/CAE has a problem? Thank you for you input, much appreciated.
