Create multiple parts geometry from an imported geometry ??

[ateshian]

Hi,

Typically I export meshes from Cubit into Abaqus (.inp) format. If I want to mesh the geometry within FEBioStudio using Netgen, I export geometry from Cubit into STEP (.stp or .step) format.

Hi Nicolas,

I don't have a unique process for generating geometry and parts for FEBio. For simple test problems I use the FEBioStudio built-in geometry features and their associated meshing tools. For applications to biomechanics of articular cartilage (my research interest) I use Cubit (also available from Coreform) to generate meshes and I import them to FEBioStudio, where I further manipulate them using the various available meshing tools.

Hi Dr. Ateshian,

When you export Cubit meshed file, which format you export to? Because I tried to export as .k (Ls-Dyna) file and then imported to FEBioStudio; I couldn't select any node.

Hi Gerard,

Thank you for the answer, I succeeded using Abaqus and the "partition from element sets" feature.

Can I still ask what is the process you use to generate your geometry and parts for FEBio ?

Hi Nicolas,

Maybe you need to perform a boolean union operation on the various parts of your geometry in the CAD program that you use to generate the .step file?

If that doesn't work, please considering sharing your file so we can figure out the issue.

Hello,

When i'm importig my .step file it creates multiple indepent geometry that I would like to transform into -> single geometry with multiple parts: Is there a way to do so ?

Actually I tried to import from .inp but didn't work either.
