[Libmesh-users] Problems with mesh refinement

[Michael P. <pov...@in...>]

Dear LibMesh developers,
we are trying to solve a Poisson equation ( -\nabla^2 u = f(x,y) )
with libmesh. We'd like to use a mesh refinement capability of libmesh.

Unfortunatly, we find a run-time error when using uniform grid refinement.
The code of our program and eroor messages are attached in the files
poisson_refinement.C and log.out .

Could you, please, tell us if we are using correctly the refinement methods.
Without any refinement the solver seems to work well.

Thank you.
Michael.
