is it possible to change a solid/logic volume that is attached to a SD between runs?
for example, I have a sphere which is attached to a SD. Can I change the radius of the sphere between runs?
what I usually do is to delete the pointers of solid/logic/physical and rebuild them in the function called by the messenger. how can I assign the same SD used before to the new logic volume?
I tried the following but it doesn't seem to work.
************************ logicWorld->RemoveDaughter(physiDet); delete logicDet; delete solidDet; delete physiDet;
solidDet = new G4Sphere("detector",fTargetLength + 10.*cm,fTargetLength + 11.*cm,0, 2*pi, 0, pi); logicDet = new G4LogicalVolume(solidDet,Air,"Detector",0,0,0); physiDet = new G4PVPlacement(0, // no rotation positionTarget, // at (x,y,z) logicDet, // its logical volume "Detector", // its name logicWorld, // its mother volume false, // no boolean operations 0);
G4MultiFunctionalDetector* det = (G4MultiFunctionalDetector*)G4SDManager::GetSDMpointer()->FindSensitiveDetector("detector"); logicDet->SetSensitiveDetector(det);
