Hello, I am wondering how to properly leverage the benefits of the base material functionality.
I have a voxelized geometry which creates 4072 materials of varying density off of 18 base materials. I have it programmed like such:
tissues[i]= new G4Material(materialBaseName.str(),density[i]*g/cm3,9); tissues[i]->AddElement(eH,0.036); tissues[i]->AddElement(eC,0.165); tissues[i]->AddElement(eN,0.042); tissues[i]->AddElement(eO,0.432); tissues[i]->AddElement(eNa,0.001); tissues[i]->AddElement(eMg,0.002); tissues[i]->AddElement(eP,0.100); tissues[i]->AddElement(eS,0.003); tissues[i]->AddElement(eCa,0.219);
However, my code is still very slow after run/beamon. Currently, the GetMaterial function runs through all 4072 materials during the materials scan. Does the base material only allow ease of initialization of the materials list, or is there an added benefit such as being able to claim I only have 18 materials total during the material scanner?
Thank you, Ming
