Hello folks,
I am a very new user of Gate, and want to simulate CT imaging on a mesh model. The code combines GateContrib-master\imaging\CT\classic and \misc\TetrahedralMeshGeometry examples in OpenGate. I am currently running into trouble.
A clear and concise description of what the bug is. <!> ** WARNING <!> The current TetMeshBox implementation doesn't support additional child volumes. <!> WARNING <!> Unknown process: MultipleScattering**
