I'm solving a equation del dot b grad phi = rhs by using Linear solver.
In a 2D domain, rhs = 0, b = 1e7 in the right and b = 1 in the left, whose interface is defined by another multifab. I found t…

Hello All,
I'm using what I think is a simple test case to examine multi-level refinement. I have a 101x101 grid with a domain size of 0.5m in X and 0.01m in Y. Basically, a boundary layer type g…

Hello all,
I have two issues about using cell center MLMG solver in the 3D channel flow case. Before listing these two issues, let me re-summarize the setup.
I have developed a code and am using…
