hypermesh tcl geometry determine principle

Hello everyone, I have a question to ask. I am a beginner in Tcl and am currently trying to write a script to determine whether geometry should use solid mesh, shell mesh, or 1D mesh. I am not sure what the conditions are for determining the type of mesh to use. Could you please provide some guidance or reference conditions for the geometry assessment? Thank you!

For any geometry, you can use solid mesh.

Shell mesh is used for the structure which one dimension is much smaller than the other two dimensions. See the shell theory.

Beams are used for the structure which two dimensions are much smaller than the 3rd dimension.

HTH,

Sorry, I wasn't very clear earlier. What I want to understand is how to use Tcl syntax to classify the geometry when importing a model. I want to write a script that classifies all the geometry into 1D, 2D, and 3D categories when the model is imported, so that I can proceed with meshing afterward. The key issue is determining the mechanism to classify the geometry using Tcl. Specifically, what criteria should I use in Tcl to identify and classify 1D, 2D, and 3D geometry?
