Hi everybody,
I'm planning to use the Trilinos NOX solvers (and LOCA in particular) to solve nonlinear buckling problems with special geometric boundary conditions. I started playing around with the inofficial Young-Laplace example and the latest libmesh SVN. The example works fine on a single CPU with NOX, but in parallel numeric errors occur along the interface between subdomains calculated on different CPUs - I can send some GMV output if requested. No problems occur when running the same in parallel with PETSc, and linear problems also work perfectly with Trilinos/Aztec. trilinos_nox_nonlinear_solver.C looks fine to me - could this be an issue with the EpetraVector or EpetraMatrix in libmesh?
