Re: [firedrake] Projecting function to finer mesh

Hi George,

Sorry about the Easter delay in getting back to you.

You can only project 'w' to other Function Spaces that are on the same

original mesh. Here, you are after the ability to prolong / inject between a hierarchy of meshes.

For this you can use: MeshHierarchy(coarsest_mesh,number_of_levels)

So, given your original mesh,

mesh=UnitSquareMesh(size,size,quadrilateral=True)

You can make a Mesh Hierarchy, mesh_hierarchy=MeshHierarchy(mesh,L)

That won't work on a quadrilateral mesh, will it? Only meshes of intervals or triangles? There's a test at the start of the constructor.
