Hello all,

Im an undergraduate student doing some studies for my FSAE team, and I have been getting problems with fixing a mesh I am currently working on. I cannot get my skewness angle to drop below my maximum desired number, my best mesh is at ~85.56 degrees. The picture shows the current problem (most recent fix attempt).

-when I decrease the minimum surface size on my surface custom control, it creates the problem which I have on the picture. The skewed cells just move further into the surface.
-I have tried decreasing the surface growth rate to 1.01, and it doesn't make a noticeable difference from the initial 1.15 growth rate.
-I have a volume control encasing my geometry of interest that is keeping the cell size at 10 mm, which is what the surface target size is at.
-Running the simulation give me residuals between 1e-3 and 1e-4, but I am planning on using the mesh settings I find here to iterate on the design of the geometry in question, so a robust mesh is of importance (from what I know, there is still a lot I need to learn.)

If anyone can point me in the right direction to resolving this issue that would be deeply appreciated.

Thanks.
