Hi everybody!

I'm trying to run a resistance simulation on OpenFOAM 3.0x using my own Hull generated on Rhinoceros. I followed the tutorial to export it to .STL format, but at the time to run snappyHexMesh I have this problem:

...
Scaling iteration 6
Moving mesh using displacement scaling : min:0 max:1
Checking faces in error :
non-orthogonality > 70 degrees : 856
faces with face pyramid volume < 1e-13 : 0
faces with face-decomposition tet quality < 1e-30 : 0
faces with concavity > 80 degrees : 0
faces with skewness > 4 (internal) or 20 (boundary) : 0
faces with interpolation weights (0..1) < 0.05 : 0
faces with volume ratio of neighbour cells < 0.01 : 0
faces with face twist < 0.05 : 0
faces on cells with determinant < 0.001 : 0
Successfully moved mesh

Patch points smoothed in = 14.31 s

I have tried a lot of ideas and don't know how to solve it.

Any idea?

Dear Diana,

this STL is not "mesh-able".
