I need the elastic constant for FRP honeycomb, so I just modeled and did a periodic mesh to the CAD, then imported it into MSD after entering the elastic constant for the fiber and entered the RUN option (during the run, the error has shown).

*IN LINEAR MATERIAL CHARACTERIZATION*

Hi Mugundan
You need to make sure that the mesh is periodic in xyz!
Easiest way to do that is to mesh 1/8th and reflect mesh in Hypermesh!
