I was looking at changing the density of an object already loaded in my universe. I notice that G4Material does not allow me to change the density of an already defined material
//Water G4_WATER H_2O water = new G4Material("Water",density=1.*kg/m3,nElem=2); water->AddElement(elH, nElem=2); water->AddElement(elO, nElem=1);
//Next, definition of denserWater....
//Through detector messenger: water->ChangeDensity(...) //Function not available in geant
However I found I could do something like this:
//I am guessing I should call G4RunManager::GetRunManager()->GeometryHasBeenModified();
Is there a difference between these functions? Which is correct? Thank you!
