hi, I implemented HYPRE preconditioner for my study due to the fact that without preconditioner, PETSc solver will take thousands of iterations to converge for fine grid simulation.
with HYPRE, depending on the parallel partition, it will take HYPRE forever to do anything. observation of output file is that the simulation is hanging with no output. Any idea what happened? will post snippet of code. -- Hao Zhang Dept. of Applid Mathematics and Statistics, Stony Brook University, Stony Brook, New York, 11790
