Hello all,
I am trying to generate a mesh with snappyHexMesh, in order to do that I drawed a STEP and from that an STL file with gmsh. the STL looks good in surfaceCheck, the problem is I don't know how to define boundaries on this STL file. I would also like to divide this STL to multiple pieces in order to have more freedom in the meshing phase. Anyone knows how to do it in a simple way? thanks to all for the help Riccardo |

Hi Riccardo,
have a look to these links: https://www.youtube.com/watch?v=ObsFQUiVi1U https://www.youtube.com/watch?v=1zQbU-E4k1U they should help you a lot. Anyway, someone uses to define groups of faces into Salome, export them into step files, to generate the 2D meshes then save them as stl (better quality). Remember that by this way, there's a sort of bug and before you can use them into OF you have to scale the stl by using surfaceTranformPoints open foam utility. Code:
surfaceTransformPoints -scale '(0.001 0.001 0.001)' <surfaceFile> <output surfaceFile> |
