Hey guys!
I'm relatively new to OpenFOAM and this forum, but I hope I follow all the rules with this question. I have a huge stl file (50GB) that I'm working on. I want to run blockMesh and snappy, but for this I need the vertices of the stl-file. Since it is so huge, I cannot open it in paraview to get the vertices - my paraview always crashes. At the moment, I use the numpy-stl package like this: Code:
import numpy from stl import mesh mesh = mesh.Mesh.from_file("my_stl_file") mesh.max_ Please help |

I'm not sure to understand what you mean by vertices, but if you are interested in getting the bounding box of your STL in order to set your blockMesh size, you can use OpenFOAM surfaceCheck utlity.
Hope this helps, Yann |

Yeah, that's it! I meant to extract the bounding box (in the blockMeshDict it's under 'vertices') and surfaceCheck seems to do exactly that! Thanks a lot!!

And it really is much faster than the numpy-stl solution! So thanks again, Yann!
