I’m running a gem simulation based on the example found in Examples/Elmer/lem. I modified the gmsh code so I could get a double and a triple gem foil cell. When I simulate an avalanche with the single or double foil geometry I get some nice avalanches, but when I run the triple foil geometry and get the following warning message and the simulation doesn’t seem to move on:
No convergence achieved when refining internal isoparametric coordinates
at position (0.00213346, 0.00276998, -0.202893).
The position showing above is located inside the gas volume.
What does this warning mean and how can I fix it?
