I'm simulating fields radiating from a flat conductive coil. Below the coil is silicon, above it vacuum. The meshing produces highly elongates voitices and puts them in a round pattern even above and below the coil. The screenshot below shows the mesh and H-field in an (non-model) plane perpendicular to the coil. As can be seen from the screenshot the meshing creates and artificial periodic and curved pattern in the magnetic field which doesn't represent real physics. How to improve the mesh to have more regular vortices and a more gradual increase in vertex size away from the coil? I did change "Minimum Number of Passes", "Model Resolution Length" and curved surface meshtng resolution but none of these optons improved the mesh.

It seems that the mesh generation is occurring this way because there are no objects in the vacuum space, meaning there are no starting vertices or midpoints for the Initial Mesh process.
How about placing several small vacuum blocks within the vacuum space? These small vacuum blocks could act as starting points when generating the Initial Mesh, potentially mitigating the mesh generation issue.
