UMAT subroutine development

[masithuf]

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.

As the message says, you are simply visualizing a variable that is unavailable. Select one of the appropriate variables from the drop down menu in the Viewer.

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.

Try to run the input file with an in-built material model (say, linear elastic) and see if you encounter the same issue.
