Dear Chris,

thank you very much for your answer!
So in fact this means, that the only possibility to create a geometry
in FLUKA is to use the given bodies like spheres, cylinders, planes
and cones? Are there no other ways to import directly geometries like
3D-wavefunction (.obj) or other files of this kind to FLUKA?

Thanking you in advance!

Best regards,

Kilian

Currently you can only use those models as a mockup or 3D template in SimpleGeo, while modelling your actual geometry with CSG methods. This way you can ensure that the geometry that you've built is matching a 3d CAD model for example. However, you cannot simply export the CAD model via SimpleGeo to FLUKA because this type of surface models is not supported by FLUKA's geometry kernel.
