I am trying to build material with new density out of copper and cannot get over a strange error:
G4NistManager::BuildMaterialWithNewDensity ERROR: New material <LightCu01102> cannot be built because material with the same name already exist
Then it throws an exception. The code is:
density = 2.24*g/cm3; MishMash = nist->BuildMaterialWithNewDensity("LightCu01102","G4_Cu",density);
The strange "LightCu01102" name is such because I tried different weird names to make sure it does not accidentally coincide with something.
Could anybody, please, advise me on what is happening and what to do about it.
