Define the Mesh Controls

Use the Mesh Controls tool to define regions with a user-defined volume element size.

Important: All other mesh controls in the model are defined relative to the far field size, and must be a power of 2 of the far field size. For example, if you define a far field mesh size of 1 m, the available refinement sizes will be 0.5, 0.25, 0.125, etc.
