Hello,
I am solving a FSI finite element matrix vector system. I am using GMRES with glut in AztecOO. It appropriately solves it for 1,2 and 4 processors on my local machine, which with 3 processors it cannot bring the residual down below 1e-1. I was wondering if this could be an issue with the ilut preconditioner, since it says convergence depends on the domain decomposition, or if it is possible there is a bug in my code?
Thanks,
Danielle
