Hi foamers,
I'm having hard times with SHM. I'm trying to make a 2D mesh, as shown in the wingMotion tutorial. Therefore, I'm implementing a mesh with SHM from stl files exported by Salome. The problem is that snappyhexmesh does not remove the mesh made by blockMesh. I think that the problem is that the stl files do not make a watertight mesh. However, how can I be sure about that it? I've seen that the utility surfaceCheck can be used to do this check, but it expects only one argument (i.e., one surface). So, the question is: how it is possible to check if all my stl files (which represent surfaces) make a watertight solid? Thanks by now Franco ps: in the attached file, you can find my case Last edited by fracasce; April 19, 2017 at 20:12. Reason: changing email notifications |

I realized what was the error in SHM: in order to avoid the problem mentioned above, it is necessary to define the level of refinement for all the surfaces (and not just some of them, as I did).
Hope this answer can help!! Franco |

Yes. All surfaces must be defined in refimentSurfaces.
