Hello,

I have been trying to mesh a relatively simple geometry with the snappyHexMesh utility. Even though I have gained some experience with the utility as I have been working on a project for a few months and have successfully employed it a number of times for more complex meshes,however, in this case the mesh generation has become a bit abstruse for me. The problem is that even though the mesh for the given geometry is being generated, the background mesh, however, is not removed at the end of the meshing process as can be seen in the image attached herewith.

I have tried several measures, namely, tweaking values for locationInMesh and tolerance, and trying several background meshes of different sizes, among others. I have also searched for similar posts, but was unable to find any pertinent one.

I entreat the respected members of the community to kindly guide me on this issue, make me aware of the mistake(s) that I have made, and possibly direct me to pertinent posts. Below is the link for the case at hand and I would be highly grateful for any suggestions or tips.

Kind regards,
Mohd Shaeq

Hi, i would suggest adding
""
locationInMesh "insidePoint";
""
on the "castellatedMeshControls". If i understand correctly, this tells to snappyHexMesh that the volume of interest is inside the surface so to stop after meshing the surface.

Hi Fotis,

Thank you for your kind suggestion.

I was able to solve the problem by regenerating the STL-Mesh in Salome and increasing the refinement level of the given surface.

Kind regards,
Mohd Shaeq
