I'm trying to build a gas mixture as a material for my detector, so I've tried first to use an example of gas mixture of the Geant4 manual (air), to understand how it works. My code is the following:
G4double a = 14.01*g/mole; G4Element* elN = new G4Element("Nitrogen", "N", 7, a);
a = 16.00*g/mole; G4Element* elO = new G4Element("Oxygen", "O", 8, a);
G4double density = 1.000*g/cm3; G4Material* mat = new G4Material("Air", density, 2); mat->AddElement(elN, 70*perCent); mat->AddElement(elO, 30*perCent);
Running this code gives me the following error:
-------- EEEE ------- G4Exception-START -------- EEEE ------- *** G4Exception : mat036 issued by : G4Material::GetZ() the Atomic number is not well defined. *** Fatal Exception *** core dump *** -------- EEEE -------- G4Exception-END --------- EEEE -------
Probably there's some silly detail I've not noticed, can anyone help me? Also, why is the code trying to get Z from a material which is a mixture of different materials? Thank you for your help
