Meshing RVE of fiber reinforced composite for muscle tissue modeling #192

Description

Hello Nick,

I’m currently exploring GIBBON for my thesis work, which involves simulating aspects of muscle tissue. Would it be possible to recreate a meshed model, similar to the one attached using GIBBON? It's modeled using two differently sized 3D representative volume elements. The elements are periodic, so the large RVE is a multiple of the smaller one. Both
RVEs are discretized with linear fully integrated hexahedral elements.

I have tried doing a 2d face mesh of the rve using multiRegionTriMesh2D, with the thought of being able to extrude it to form a 3d mesh. But I ran into the issue bellow when trying to "substract" the quarter circles in the egdes from a rectangle enclosing the RVE, as the boundary curves input .

The third image is the closest I have gotten, but then I ran into the issue of the nodes not being shared on the interfaces between the fibers and the matrix.

Is there a way to circumvent those issues in order to be as close to the original meshed model?

Thank you very much for your time. I appreciate any guidance you can provide.
