Hello,
I am relatively new to this programming stuff. I want to import a mesh from
gmsh to solve the tutorial example 21 (flow through porous medium). I followed
example 5, but i keep on getting this error message;
An error occurred in line <1955> of file <source/dofs/dof_handler.cc> in
function
void dealii::DoFHandler<dim, spacedim>::distribute_dofs(const
dealii::FiniteElement<dim, spacedim>&, unsigned int) [with int dim = 2, int
spacedim = 2]
The violated condition was:
tria->n_levels() > 0
The name and call sequence of the exception was:
ExcInvalidTriangulation()
Additional Information:
(none)
Can someone pls explain this to me, and how to fix that???
Thanks
Ricky
