[snappyHexMesh] Feature edges are not accurately represented

WJPeace1 · May 17, 2022, 10:31

Hi all,

Possibly a very silly question but I cannot seem to get a well-fitted mesh on my cylindrical geometry shown in the attached image. The edges are not accurately represented on both the "cuts" into the geometry and the circular section itself.

How would I be able to solve this issue? Many thanks in advance!

Will

Hey,

without seeing your surfaceFeatureDict and your snappyhexmeshdict it is quite hard to help you out. Just by looking at the attached picture i would guess the background mesh might be too coarse, surface refinement too low, or explicit feature snapping not activated.

Maybe this helps?
