I am trying to import a simple extruded shape into LS-Dyna whilst keeping it as a solid. However the model always opens as a hollow shell when in LS-prepost. Does anyone know how to keep it as a complete solid.

Hi

 

Yes a solid is a collection of faces in LS-PrePost (LSPP).

 

All the best

Hey Erik, for the simulation I am trying to run I need the object to not be a shell with the inside being hollow but as a filled solid. The AI assistant mentions a setting in Moldex3D for file transformations like "Solid to Solid" and "Solid to Shell" in version 4.9 but I could not find Moldex3D in this version of LS-Prepost.

Hi

Ultimately we need FE/mesh.

That is the way it is in LSPP (a solid is a collection of faces) – we still can mesh this (volume/solid made of bunch of faces), with 3D solid elements (LSPP first meshes the faces/skin and then the interior volume with 3D solid elements). See tutorials on meshing in LSPP.

 

You can also use WB LS-Dyna to create the mesh as .k file and import that into LSPP.

All the best
