Modelling Sandwich panels

Recommended Posts

HI there

 

I have imported a 3D CAD model to HyperMesh that includes sandwich panels and I would like to ask the best way to mesh these? I have tried using a 3d mesh on the geometry to represent the core properties, and added a 2d mesh to the faces to represent the skin properties (created by using the 'find faces' tool). When I try and solve however, I get multiple 'Error 14: Missing Property # 4 referenced by CQUAD4 # x'

Searching on here, it appears that this is a problem with the 2d mesh on the 3d nesh, so a better way to represent the panels would be appreciated!

Hi,

 

check if you have applied a PSHELL property to the CQUAD4 element # x. If the element is not compatible with the property it throws this error. Also ensure that different types of elements (shells, solids)  are assigned to different components.
