VolumeMeshExport (structured inside yarn?)

[rpenidef]

Hello,

I have a question regarding meshing that I have not been able to solve. My goal is to have a structured mesh (similar to how it is meshed for the abaqus dry fabric export) in the fabric, and the tetrahedral one (or whatever, it is not really important for my application) for the matrix part.

From the VolumeMesh export I get tetrahedral unstructured for both and the AbaqusDryFabric export does not have a matrix. Using the geometry and mesh it on my own is not a good way of solving the problem since I want to have the matrix sharing nodes with the surfaces of the yarns and avoid contact interaction modeling.

I thought that there might be a way of imposing the mesh from scripts, like the "CSectionMeshRectangular" or some sort and then export, but from what I tried...the export overrides the mesh. Any suggestion?

Thank you,

Hi,

You can use the CMesh class to generate surface meshes of the yarns. The CSectionMeshRectangular class gives a mesh of the yarn cross-section so I don't think is what you're after.

For a yarn or textile you can use the AddSurfaceToMesh or AddVolumeToMesh functions which will give you the surface or volume mesh respectively. The surface mesh is what you see if you use the Render->X-ray and the volume mesh is shown by Render-Volume Mesh. You can then use the nodes/elements from the mesh generate as you wish.

Hopefully that will get you started. Let me know if you need any more help.
