stl file problem
Hello, I'm new to snappy and want to give it a try. I ran the motorbike tutorial and everything went well. I then wanted to try with another geometry (a sphere) and compare it with my results from Star-CCM+. Here come the problems... I built a sphere in Salome and saved it in *.stl then I modified the surfaceFeatureExtractDict to extract the features (I changed the name of the file for sphere.stl). but when I run it, I get this error:
Code:

Floating point exception (core dumped)
I tried to use another program (blender) to generate the stl file but I still get the same error. I tried with a cone instead of a sphere, still nothing and now I don't know what to do. I also tried binary and ascii for the stl but it doesn't change anythig.
Here's my surfaceFeatureExtractDict:
Code:

object surfaceFeatureExtractDict;

extractFromSurfaceCoeffs

includedAngle 150;
}
// Write options

}

Any help would be appreciated
