Hej,

I have a problem with the stl fileformat and the snappyHexMesh tool. The dimensions in the stl file format are as always given in mm, because all 3D cad programs (SolidEdge V20 in my case) export the original ISO dimensions. The problem now is that snappyHexMesh uses m as input, is there any way to define a scaling factor for snappyHexMesh?

Hi Roman,

You can use the following command:

transformPoints -scale '(1e-3 1e-3 1e-3)'

I hope it works.
Best regards,

Or you can scale the stl files with surfaceConvert when you clean them

surfaceConvert in.stl out.stl -clean -scale 0.001

Yeah I was looking at that, and it will work after meshing with the same order of magnitude of the numbers and then converting the mesh.

I will try it as soon as I have my model ready. Thank you

Worked perfectly. Thanks again
