- Is SSW card able to track neutrons crossing surfaces defining universes?
Hi everyone,
I am using SSW card.
Although the manual is very clear about the fact that the cells used in SSW card have to belong to the lowest level, the manual is not that clear the surfaces.
Is SSW able to track particles crossing surfaces defining higher level universes?
Let's assume this code:
May I write
if I want to record all the particle entering the cylinder of basis at +50, -50 and of radius 2?
Or do I need to have auxiliary planes used in the universe U=20?
Moreover if I need to track particles through surfaces which have been transformed first via a TRCL, do I need to give the original surface, or the modified one. For instance, in the example above let's assume I applied a transformation TRCL at the cell 3, which surface do I need to specify
if I want to track the particles accross the lateral surface? Because I'd expect so, but when I tried a simple run it gave me error exactly saying that "surface 3012 not defined". So I am a bit puzzled.
Thanks in advance

Let's assume this code:
Code:
1 1 -1.0 10:-11
2 1 -1.0 11 -10 FILL=20
3 2 -2.7 -12 U=20
4 1 -1.0 12 U=20
C Surfaces
10 PZ 50
11 PZ -50
12 CZ 2

May I write
Code:
SSW -12 (3) -10 (3) 11 (3)
