We are writing a simulation which includes additional physics (low-temperature phonons and charge carriers) provided by an external library (G4CMP). Surface interactions in this package are implemented by way of creating either Logical or Border surfaces, to which G4CMP-specific surface property containers are attached.
When I try to write out this geometry to GDML, it aborts with a fatal error:
-------- EEEE ------- G4Exception-START -------- EEEE ------- *** G4Exception : InvalidSetup issued by : G4GDMLWriteStructure::SkinSurfaceCache() No optical surface found! *** Fatal Exception *** core dump *** -------- EEEE -------- G4Exception-END --------- EEEE -------
If I don't create the surfaces, the GDML output completes with no problem.
Are there any guidelines available for how to incorporate non-optical surfaces into the GDML output? Is there a way that we could improve, for example, the surface property containers in G4CMP so that they'd be recognized and writable by GDML?
