Hello. This really isn't a bug, but I think it should not give such a ridiculous error.
If I login to my linux machine and run the Stokes DEMO, I get this: =================================== Solving linear variational problem Matrix of size 25140 x 25140 has 730140 nonzero entries. Applying boundary conditions to linear system. Applying boundary conditions to linear system. Applying boundary conditions to linear system.

[0]PETSC ERROR: See docs/index.html for manual pages. ======================================== If I run it on the actual linux box, then there is no problem. The reason it doesn't work in the other case is that there is no display (duh). Is there a way to make dolfin just output a message if there is no display, instead of that giant error message? - Shawn _______________________________________________ DOLFIN-dev mailing list DOLFIN-dev@fenics.org http://www.fenics.org/mailman/listinfo/dolfin-dev
