re-smooth with "penta_6 freeze". Maybe with Laplace on.

Otherwise make new prisms with less "total height". Optionally set Prism Height Limit factor to 0.9 (or less than 2).

It might also help to do the following steps:

1. create the tetra-mesh like usual 2. smooth the surface mesh with laplace while switching the tetras to "float" 3. smooth the whole mesh without laplace 4. Create the prisms

Doing that the surface mesh might improve and so might the prisms.
