I am a newbie to Elmer ....
I am trying to run the simplest, 2D heat transfer problem,
but running into solver problems.
A square, with the opposite sides at different temperatures.
I successfully entered the first example in the ElmerGrid manual
I loaded that example into Elmer GUI.
I was able to split the edge into four edges, and assigned different temperatures
to two opposite edges.
When I run the solver, I get this error:
Program received signal SIGSEGV: Segmentation fault - invalid memory reference.
Backtrace for this error:
#0 ffffffffffffffff
Any ideas?
Thanks,
George

Hi,
in general, it is advised to use an external mesher (gmsh, Salomé) to prepare the mesh.

I guess the mesh is too fine/dense for the limited memory of your computer calculation. Try with a coarser mesh.
2. Elmer Files uploaded here can help the experts or other users to debug your issue. At least you need to provide the geometry/mesh and sif files.
