Dear Fenics,
after following this:
http://fenicsproject.org/documentation/dolfin/1.1.0/python/demo/pde/navier-stokes/python/documentation.html
I think this, doesn't work anymore:
# Use amg preconditioner if available
prec = "amg" if has_krylov_solver_preconditioner("amg") else "default"
Can you be a bit more specific? What is the error message you get?
I'm very sorry, but I forgot the exact error message. However, the
demo in /usr/share/fenics didn't contain that line at all and I simply
used the file there. I remember that the the calling function had
"amg" as argument per default later. That was the solution. No
wrapping call using has_krylov_solver_preconditioner anymore.
Thanks for the immediate reply,
Roland
PS: I'll have a look at it at the weekend and can recreate it maybe then.
