I would like to refine a 2D mesh in the pde toolbox using the "new" flow. I am basically looking for the new version of the old function "refinemesh"

Sorry, the new way to do it is to construct an entirely new mesh using generateMesh using a smaller Hmax value. It is indeed different than using refinemesh, but I believe that it should work as well.

Indeed, this doesn't seem straightforward. You can extract the mesh using meshToPet, then use refinemesh as you like. But your PDEModel object will no longer contain the mesh, so you would have to use the older workflow from there on.

What if you want to refine the mesh in only one direction? I have a 3D cube and I want a finer mesh in only the z-direction. Can I do this and solve with the PDE Toolbox?
