Hi everyone, I’m solving a finite element (FEM) problem in Julia and need to scale up the code. The main issue for me is solving large sparse linear systems in parallel. I know that in CFD and FEM communities, many people rely on PETSc for scalable Krylov solvers and preconditioners, and Julia has…

How complete is PETSc.jl for parallel linear solves in FEM/CFD applications?

I’m also looking at these packages for scaling topology optimization as well.
