Hoping we can get some help on this. We want to do electromagnetic simulations and need a regular finite difference mesh to do so. We want to be able to export a model (from e.g., Blender) to a finite difference grid and specify the start, stop, and step of each x, y, and z axis.
We tried this with Blender using the re-mesh > blocks modifier. It looks promising, but it does not yield a dense mesh as needed for EM simulations.
We are open to paying for tools, but the ~$15k cost of the big names (Altair, etc.) are out of our reach at the moment.
You can try exporting it from blender as step. But Netgen also needs watertight geometries for meshing, also you Netgen gives you unstructured meshes, not regular FD ones. but why finite difference and not FEM?
Thank you for your response. We are using FD ones because it is what the EM solver supports. I do agree that FEM would be more flexible.
The watertight requirement you mention poses an issue for us since our models won’t be closed solids. If you have any other insights, I would be happy to hear them. I appreciate you taking the time to reply!
