I‘m going to run a crystal plasticity model with XFEM crack. the material properties are defined as USER MATERIAL. when the job was submitted, an error message was appeared :"39600 Elements are missing elastic property reference. The elements have been identified in element set ErrElemMissingElastic PropRef". I was confused by this message, because the elastic and plastic deformation were descripted in UMAT. but the job can't be submitted sucessfully.
Any response are appreciated, thanks you!
Dear Zhang,
You can input properties in Abaqus software also. Then UMAT will overwrite those properties even if they are wrong. This should solve the problem.
Hi Wenjie Zhang,
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.
