Hello everyone,
I have a 3D mesh in the [p,e,t] format, as described here: https://www.mathworks.com/help/pde/ug/pde.femesh.meshtopet.html
My point is to include this mesh on the PDE toolbox to perform numerical simulations. Can someone tell me if this is possible?
Thanks in advance.

You can attempt to use geometryFromMesh function to import geometry as a mesh (also retain the original mesh).

Hi Ravi,
Thank you for the response. In my case, I've used the gmsh software to export the mesh and read it on MATLAB. The geometry is a little bit complex because it is a multi domain geometry. I've already tried using geometryFromMesh functon, but one important information is missing: the vector ElementIdToRegionId. Can you tell me how I can ontain this information? It seems that the .msh file does not have it.
Thank you.
Regards,
Fernando
