Topic: Internal error running model on Atena 3D Engineering

Dear User/Admin.,

I'm using Atena 3D Engineering to model a push-out test. When I run the model it can converge on step 1 and 2 but on the third step it stop and open up a window with the following message "CCMaterialExtendedAExc: CC5ParamYieldF::project_stress_on_f - division by zero". I don't know what could be wrong neither what it means.

If someone could help me I would appreciate it very much.

Thanks in advance,

Raquel Painço
