I am not sure this is the proper forum, but I couldn't find a better place for my question. As stated in the Release Notes of Geant4 5.0, the Materials setup procedure was changed. Specifically, "G4Material: removed constructors with chemical formula." If I understand the terminology correctly, this is the constructor I was using a lot. For example, here is how I used to make water: G4String name; // name of an element G4String symbol; // chemical symbol of an element G4double a = 0.; // mass of a mole; G4double z = 0.; // number of protons; G4double density = 0.; // density; G4int nComponents = 0; // number of components in a material G4int nAtoms = 0; // number of atoms in a molecule G4State state = kStateUndefined; // state of the material // -- Elements name = "Hydrogen"; symbol = "H"; z = 1.; a = 1.01*g/mole; G4Element* H = new G4Element(name, symbol, z, a); name = "Oxygen"; symbol = "O"; z = 8.; a = 16.00*g/mole; G4Element* O = new G4Element(name, symbol, z, a); // -- Material from elements: chemical molecule // Create a material from a combination of elements and/or materials // subsequently added via AddElement and/or AddMaterial name = "Water"; density = 1.000*g/cm3; nComponents = 2; state = kStateLiquid; G4Material* H2O = new G4Material(name, density, nComponents, state); H2O->AddElement(H, nAtoms = 2); H2O->AddElement(O, nAtoms = 1); If this method is not available in Genat4 5.0, what are the recommendations for creating such thing as water (not to mention all other chemical compounds)? (Heck, I really liked the method I used above, and if it is really gone, that's a pity). Thanks in advance, -- Elena.
