FEA Issues with Voronoi-Based Bone Scaffold Mesh in COMSOL

Grasshopper
1

We designed a bone scaffold using the Voronoi algorithm in Grasshopper and exported the model as an .stl file to COMSOL for (FEA). The scaffold is a complex mesh structure, but when importing it into COMSOL, the software doesn’t recognize it as a solid, leading to issues during the stress analysis. Instead of analyzing the entire structure, COMSOL only detects a few curves. How can we resolve this issue to ensure the scaffold is correctly interpreted as a solid in COMSOL for accurate FEA?

Thanks in advance

could you please post the STL file or -even better- the GH file used to create the geometry?

you will agree it’s pretty difficult to guess if / where the problem might be from plain text :upside_down_face:
