My fluid domain is the volume outside of a sphere (solid) that exists inside a cube (solid). The following mesh tools were used: Surface remesher, trimmer, and prism layer.

I've cut the domain in half, so the depression (bowl) is half of the spherical shell.

Please note the irregular elements of the mesh in the 6 prism layers and at the interface between the outermost prism layer and structured hexahedral elements.

What is this type of meshing error called and how can it be mitigated?

Thanks for your time,
