Hello together,

After using Surface meshes and Delaunay to build up my mesh for a while, I found that the unstrucutred mesh is too coarse in a region of interest.
My solution for this is to implement an inflation layer.

My problem with it is, that I am unable to integrate a prism mesh during the usual surface + Delauny meshing process. It fails. (Error: open edge encountered. prism terminated prematurely) or it just puts the error after a certain layer.
Also trying to add a prism layer after surface and Delaunay volume meshing fails.

So, I switched to Octree with prism (and also tried adding it after but the outcome is similar), which tends to work, however, now I have these local misdistributed areas, in which very large elements are created that exceed the max size limit I set. See picture.

Now, my question would be that maybe someone already encountered this problem and has a solution at hand or an idea on how to go about it?

I spend a lot of time trying to change the prism layer settings and min and max size of the general mesh settings, but this problem persists.

Thank you in advance and for reading!
