Hello I am struggling to solve an incompressible solid mechanics problem using a meshfree code based on Moving Least Square approximations. My knowledge of solvers and preconditioners is quite limited. But it seems that Additive Schwarz or Gram Schmidt preconditioners together with GMRES is a good choice - yet still not good enough in my case. So, I was experimenting with exact (LU) solves in each subdomain which does the trick but the memory need is significant. Now, my question is what purpose serves the function PCASMSetOverlap and could it be used to improve this setup in any way? Thanks.
