I have a physical volume called "fuel" composed of 841 elementary volumes; addition to the physical group is done automatically in the for loops. The "fuel" geometry is attached. I want to remove one of the elementary volumes from the physical volume. Through the GUI, I know its ID. With the information I have, can I do what I want to do?

Physical Volume(1) -= {1,2,3};

Add the elementary ids to a list 9selectively), and only create the physical later.
