Hi,

We have run the same 2D Navier-Stokes:
dolfin-snapshot/src/demo/solvers/navierstokes/benchmark
in different mashines: Linux-Debian and Linux Red Hat. The
strange thing is this: the program works perfectly in Linux Red Hat,
but it does not work in Debian. We did not change anything,
it is exactly the same program in different machine.

The error in Debian is:
....
Applying Dirichlet boundary conditions.
Boundary condition applied to 17 degrees of freedom on the boundary.
Solve linear system: continuity
Solving linear system of size 3466 x 3466 (Krylov solver).
*** Error: Krylov solver did not converge. [PETScKrylovSolver.cpp:113:
solve()]

Do you know what is the problem?

Thanking in advance,
Maziar and Murtazo
