[Trilinos-Users] Aztec OO installation question

[Nikhil Kriplani]

Hi,

I just installed Trilinos 10.0.2 and want to enable AztecOO's direct
solver (plain LU) option in my code. My question is, what should the
line in the do-configure script look like?

I have tried
-D Trilinos_ENABLE_AztecOO_Azlu:BOOL=ON

and different capitalizations of the AZLU characters, but none seem to
have worked.

The trouble I am having is that when my code uses NOX to solve a
nonlinear set of equations, NOX calls AztecOO and it gives me several
warning messages about the GMRES matrix being ill-conditioned, and
eventually the solution just breaks down. I wanted to try a few other
linear solver options before I delve deeper into the setup of my code.

Thanks.
