I want to solve a PDE equation on a specific mesh using assempde

From my polygonal geometry I used mesh2D from the matlab file exchange to create my mesh and then I "manually" rewrote them so they are on the same format as the canonical 2D matlab mesh data.

So here I am with my [p, e, t] data which displays nicely when I call pdemesh(p,e,t) Then I'll write my pdebound function to apply my boundary conditions but then I wonder :

How do I give that information to assempde ?

Indeed I need to create a model using createpde and then attach it my geometry.

I've seen that there's a function called geometryFromMesh but the documentation says that it's for 3D geometry whereas mine is only 2D.

I can't figure out the workaround.. Any ideas ?

Thank you.
