[CortexShedding]

I feel like one of the biggest hurdles to a wider adoption of OpenFOAM to the industry is its well known struggles with the creation of good prism layers. My work involves the external aerodynamics simulation of pretty complex geometries and I find OpenFOAM to be perfect for me if I can reliably generate prism layers. However, what happens often is the large amount of time I spend generating prism layers fiddling with the settings in SHM is in the end more expensive than the extremely quick meshes offered by commercial meshers. I have also tried cfMesh but I am never able to generate good quality meshes with that.



So, I was wondering if anyone here knows how commercial meshers implement prism layers and whether something like that can be implemented in SHM by modifying the code? I have also read that enGrid was really good with prism layer generation but it's very much abandoned these days.



I realize that if it were easy, it would have been done already, but I don't mind working on this over the weekends for a while. I also understand that the code is all out there to see for myself but I feel like a high-level overview from someone who has experience with this would really help me get started in the right direction.
