I have tried to use the "Lxe" example to build my own BGO scintillator. However when I try to change the material in the detectorconstruction
//Liquid Xenon // fLXe = new G4Material("LXe",z=54.,a=131.29*g/mole,density=3.020*g/cm3); //old material definition fLXe = G4NistManager::Instance()->FindOrBuildMaterial("G4_BGO");//new material definition
the example can compile, but I get an error at runtime:
Idle> /run/beamOn 10 /run/beamOn 10
-------- EEEE ------- G4Exception-START -------- EEEE ------- *** G4Exception : GeomMgt0002 issued by : G4Region::ScanVolumeTree() Logical volume <scint_log> does not have a valid material pointer. A logical volume belonging to the (tracking) world volume must have a valid material.Check your geometry construction.
*** Fatal Exception *** core dump *** **** Track information is not available at this moment **** Step information is not available at this moment
-------- EEEE -------- G4Exception-END --------- EEEE -------
*** G4Exception: Aborting execution ***
just changing the material shouldn't induce such problems I believe, so I am not sure how should I act
any idea would be appreciated
