How to set up matx27 material?

Joao Rabelo_20329

Hello guys, 

I'd like to ask for help. 

I'm running a geometric nonlinear analysis to analyze a rigid foam. 

I'm going to compare my numerical model with experimental data. 

In the experimental test, the material broke.

I wanted to implement the material as MAT1 with the MATX / MATX27 extension, for this I have already seen that I need to configure in the loadstep the expdyn subcase, I don't know how to do that, I don't know how you set up this type of analysis.  

Can anyone help me? 

Thanks.

Hi,

Can you please let me know what Altair product you are using so that I can transfer your query to the proper forum?

Hi,

I'm using hypermesh and the optistruct solver.
