[Gmsh] Comparison of different meshes

[Rohracker, Maurice]

Dear GMSH user and developer,

I created two meshes for a box with a spherical inclusion around the 
origin, one with tetrahedra and one with hexahedra. For both, I created 
a simple load case in Abaqus and compared both results in a short report 
(see attached). In the report, a more detail explanation of the load 
case is given as well.

Do you have any idea, why in the hexahedral case, the stress results are 
not that smooth like in the tetrahedral case? Could it be that I missed 
some option while creating the hexahedral mesh? Are there any options 
which could improve the mesh and such also the results? Or are these 
things related to the simulation I am doing?

Do you have any similar experience with such behaviour?

We are using GMSH 4.4.1.

If you need more information, please let me know.

Thank you very much in advance.

Best regards,
