Dear Kilian,

I'm afraid that SimpleGeo provides some features (e.g. surface or b-rep models) which are not supported by FLUKA at all. 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.

Cheers
Chris
