I’m going to use XFEM crack to run a crystal plasticity model. USER MATERIAL describes the material properties. An error message came when the job was submitted: “Elastic property reference is missing for 39600 elements. The elements have been found in the ErrElemMissingElastic PropRef element set “.. This warning surprised me because elastic and plastic deformations were described in UMAT. However, the job cannot be successfully submitted.
Thank you for your time and consideration.

Hi,
This error could have two reasons:
The material you defined in the subroutine doesn’t match the geometry and the section you defined. For example, your model is solid, and the material properties you defined are for the shell model. the second reason is you may have assigned the wrong element type in the Mesh module. Check the simulation and see which one this is.
Also, I recommend checking the links below. They will help you write the UMAT subroutine and learn more about it. It’s worth a look.
