Thank you Christophe for this quick answer!
What do you mean by setting the size directly? Is there another way I
can set all shapes to be hexs instead of tets? I looked it up in the
Archives but couldn't find.
Thank you

Hi,
I am using GMSH 4.5.6 to generate a 3d mesh. I used the following 2
lines in the .geo file to ensure that no element would have a jac.<0.
Mesh.ElementOrder = 2;
Mesh.HighOrderOptimize = 1;
It unfortunately didn't work for me. The mesh is generated, but the
software failed (froze). Is there another way I can force all
jacobians to be positive when creating my mesh?
It works fine here. However you should remove
"Mesh.SubdivisionAlgorithm = 2;" (and set the sizes you want
directly), as this makes it harder for the optimizer.
You can also use "Mesh.HighOrderOptimize = 2;", which will apply a
global elastic smoothing step before the brute-force optimization.
