Independently of the type of mesh that i am using the prisms that are created have a bad orthogonal quality &#8211; this happens only when there is a sharp angle in the geometry (~ 90 degrees) or where the mesh transitions between the regions of different first layer thicknesses. All of the zones have the same amount of layers and I am using the last ratio method. I tried meshing and then using auto node move but with no success. I am attaching the screenshot of the geometry and the bad prisms. Is there another way of fixing this other than rounding every corner i have in the model?<img loading=\"lazy\" decoding=\"async\" title=\"Bad prisms\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/08\/16-08-2023-1692209402-bad prisms.PNG\" alt=\"\" width=\"745\" height=\"385\"><img decoding=\"async\" title=\"Mesh overall\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/08\/16-08-2023-1692209467-mesh_overall.PNG\" alt=\"\"><img decoding=\"async\" title=\"Mesh, closer\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/08\/16-08-2023-1692209484-mesh_closer.PNG\" alt=\"\"><\/p>\n<p>My surface mesh quality was perfect (skewness &lt; 0.5).
