Sandwitch Panel modeled with Hex element core.

[chokka]

I have a nastran FE data contains many parts. And, I have got F06 file based on my prelimnary analysis. I want to to findout MOS for one particular panal in HS, based on my nastran FEA results.  The panel that I am interested is a sandwich panel, was modeled with core as a Hex elements and skins as a shell element(pcomp) in Nastran. If I import this FE data in HS-pro, can I calculate MOS for this panel. How HS-Pro treats honeycomb sandwich panel modeled with combination of shell and solid elements?

Thanks

Hypersizer V5.7.6 will import a Nastran deck with Hex elements for the core and shell elements for the face sheet. The panel is imported into Hypersizer in a very similar way to a shell element. After importing you will have two face sheets and a core defined for your component.

MAT8 properties and a PCOMP define the face sheet material and lay-up
MAT9 properties define the core

Note: Hypersizer simply reads the MAT8 and MAT9 ID. Ensure you have the face sheet and core materials set up in the Hypersizer database prior to importing your FEM. The materials can be defined and assigned  after import if necessary.

Also, note the z direction for the face sheet abnd core must all point in the same directions.
