Question Tesselated solid overlap issue leaktest. 

Forum: Geometry
Date: 07 Mar, 2017
From: David Takacs <David Takacs>

We have a geometry in SolidWorks which we would like to import to geant4. The way we do it is the following: 1. We export the files from SolidWorks in a .stl format 2. Import them to blender, and export them as a .raw format. Raw format builds up our geometry using triangles. 3. After importing the raw files to geant4 as G4TesselatedSolid's we get overlap errors when running it. We will attach photos of the overlap error and pictures of where the overlap actually is.

Attachment:
As you can see in the attached pictures we have 2 concentric tubes and since the circles are polygons they overlap where the circles wouldn't overlap.

Questions: We have radiation sources inside the tubes we a detector set up around the tubes and we would like to test leakage radiation. How could we solve this problem so our leakage test will be realistic?
