Hi, all.
I am curious about whether i can use MeshWorker: class for FESystem.
I am trying to solve system,
that I need to solve 'stokes flow' and then use velocity solution to solve
other scalar transport equation using DG method
that looks like

Dear All,
I developed a simple code which just import a simple UNV file, then prints
the mesh's boundary_ids and material_ids.
The problem is that the output is EMPTY.
The mesh is 3*3*3 and hexahedral, made with SALOME. There is two integer
group_ids attached to some of its faces and cells.
I suppose your heat source is discontinuous wrt (x,y). Does your mesh exactly
represent the discontinuity in the circular case ? If not then you will be
introducing a lot of error since your source terms will not be accurately
approximated. To calculate the source terms in the galerkin method,
I am trying to solve the heat equation for round heat sources and very
small diffusion coefficients (<1e-7). Now when comparing the results
between round heat sources and square heat sources, I get the following
result for round heat sources:
