[Libmesh-users] problems with mesh refinement

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

Dear Libmesh developers,
I use Libmesh in order to integrate a function over a 2D mesh.
The idea is to use the adaptive mesh refinement of Libmesh.


In order to do this, I define a ficticious equation system and assign my 
function as a solution of it.
Then I integrate the function.
After that, the mesh is adaptively refined, the function is recalculated 
on a new mesh and the integration is performed again.
This is done untill the convergence is reached.

For the sake of accuracy I use a second order mesh.

If I compile a code in the optimized mode, everything works.
However, in the debug mode I get a run-time error:

Bad element ID = 49, Bad neighbor ID = 13ERROR: Ancestor Element at 
level 2 found ancestor neighbor at level 1
[0] src/mesh/mesh.C, line 471, compiled Jan  8 2007 at 15:43:37

What can it be?
If you need a more detailed information, e.g. mesh files, I should be 
happy to send it to you.

Thank you,
Michael.
