Hi guys,
I was wondering if it’s possible to create a mesh combining meshL and normal mesh or if there’s a way to make these two meshes compatible.
For exemple, say I have a triangle
meshL would be the mesh over the edges of this triangle
mesh would be the mesh inside the triangle
Is there a way to guarantee that nodes from mesh are nodes from the meshL?
If anyone know something about this, I would be greatful!
Thanks!
Perhaps the emptymesh command is helpful?

Unfortunally, no.
What I need is two independent meshes but they need to be compatible.
For example, on the first mesh I need a polynomial space over the partitioned edge, it would be something like a P0 over each pice, in total, 10 dofs
For the second square, P0 over the edges would give me 20 dofs
But the mesh inside, I can refine as much as I want, as long as the nodes for the edge partition matches the mesh in the volume
I believe what you are asking for could be achieved with emptymesh + movemesh, as long as the geometry is as simple as the one you’ve sketched.
Suppose the lower triangle is called ThL. Then do the following to create the upper triangle:
emptymesh to create a copy of ThL without any internal triangles: (e.g.: ThLcopy = emptymesh(ThL);)movemesh to reflect this copy across the diagonal edge.
