Controlling the number of Elements in Gmsh 2D

1

Hello,

I’m trying the mesh this geometry defined by 32 boundary nodes using Gmsh 2D as hypothesis. I need it to be only quads.

But the problem is not matter how I adjust the parameters the number of elements does not go below a certain value. Is there anything I can do about this?

Hello,
I think your issue comes from the “Element size factor,” which is set to 1. This means that all the elements end up being roughly the same size. If you want to be able to coarsen toward the center, you need to change this parameter >> 1

Thank you will try it!
