Good morning,

Is it possible to define the deviatoric behavior of a material when using the VUEOS subroutine? When I try to specify additional material properties, the simulation does not run and I get the following error:

"***ERROR: THE OPTION *USER MATERIAL,TYPE=MECHANICAL COMPLETELY DEFINES THE
           MATERIAL BEHAVIOR. IT CAN NOT BE USED WITH AN OPTION THAT DEFINES
           PART OF A MATERIAL`S BEHAVIOR"

I would like to run the given VUEOS example in the documentation with the Us-Up EOS and compare it to the result from CAE (i.e. under edit material->mechanical->eos->us-up), before moving ahead with my own EOS. In the latter case I can define a shear modulus, plasticity model, and so forth. Is this possible with VUEOS or must I simply write my own VUMAT which encompasses both the dilatational (EOS) and the deviatoric response?

Here is what the material definition in the input file looks like:

Thank you.
