Re: divergence?


For sequential runs use -ksp_type preonly -pc_type lu
For parallel runs you need to first config/configure.py PETSc to use
a parallel direct solver. See http://www-unix.mcs.anl.gov/petsc/petsc-as/documentation/linearsolvertable.html
for the choices.

Hello again,

I want to compare the iterative methods with direct methods in terms of time.
What functions can I use for direct solution?
