Simulation time dependet on mesh structure

Help & Support
1

Dear OGS Community,

while using and experimenting with different mesh types, I noticed that the simulation time increases significantly for quad meshes and slices (extruded 2D triangular meshes) compared to tetrahedral meshes. I also noticed that an unstructured tetrahedral mesh simulates faster than a structured one.
This phenomenon is independent of the number of elements.
Has anyone else experienced this or does anyone know how to change this or at least what might be causing it?

Best,
Kim

Hi Kim,

this is indeed interesting. Do you have two comparible simulations, say tet vs. hex, which you could upload here?
