snappyHexMesh - Poor surface
3 Attachment(s)
I'm trying to mesh an axisymmetric slender body (a finless missile) using snappyHexMesh. I have a very high quality .stl file and have modified the motorBike snappyHexMeshDict rather than write from scratch as I'm just getting to grips with openFoam. However, when I run sHM I get a very low quality surface as can be seen in the attached image for the first and second 'timestep' during sHM.
What I would like to know is which parameter in which Dict is it that controls the quality of the surface matching? I would be inclined to say that increasing the grid resolution in blockMeshDict would help. If this is so, is it possible to create a blockMesh cuboid around the missile geometry of high resolution which is contained within a larger domain cuboid? (See attached image) |
OK, so it looks like I hadn't told sHMDict to refine the surface, only the refinement area.
Before I had: Code:
refinementRegions Code:

Hi Daniel ,Have you solved the problem? Have you gotten a high quality surface? Actually I have a problem similar to you!!
Best regards, Sasan. |
