Hello,

I have a beginner question about how to have a full control of your tetra meshing.
I have a simple (3D) geometry: a cylinder with a restriction in the middle.
And I would like to create the surface mesh but with 3 different sizes of cells: one big for the beginning, one very fine for the restriction and one between these two for the end.
I tried to use the part mesh setup but the problem is that the size of the maximum element must be a power of 2 so every size that I use must be at least the double of half the size as another one, which is not what I want.
Also I tried to compute the mesh part by part with changing the scale factor each time and it work well but there was no transitions between the 3 parts which made the mesh horrible...

Do you have any advice on this problem ? Am I trying to do this the wrong way ?


Thank you
Ben
