[Trilinos-Users] ilut

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
