I would like to use the local sizing via the nglib API.
For this purpose I am using the ‘Ng_RestrictMeshSizePoint’ API.
However, so far I cannot see any effect when I generate a tetrahedral mesh using Ng_GenerateVolumeMesh.
My example is a 1x1x1 cube with 12 triangles. I set the sizing at the nodes to 1.0, and for the center point I set the sizing to 0.1 (something small). I have tried different grading values (0.1-0.9) without any effect.
Is this example too constrained/simple (e.g. because the boundary triangles are constrained)?
