Dear Barbara,

I tried to go through your code and here are my remarks:
-The USRTRACK scores are defined with Emax < Emin. You should invert these values.
-The END card before GEOEND should be activated.
-Also, the problem you have with your RPP geometries comes from the definition of the regions.
You did not define any region and the RPP represents only the shape of an object. This is why you cannot see this geometry in the geoviewer.

There are two ways to define regions:

- Either you can manually add the region in the input tab with the "region card' and write the expression leading to fill the shape (add > geometry > region).

- Or you can use the "region" button from the geometry viewer (you select the shape, you click on "zone" and then you select the area you want to define).
More explanations can be found here: http://www.fluka.org/content/course/NEA/lectures/Geometry.pdf

I suggest you to load a "basic input" by clicking on "new>basic", and modify it to get what you expect.
In this way, you will have a part of geometry already defined that you can use to get yours.

Best regards,
Thomas

Subject: [fluka-discuss]: Probably super simple

Hi!

I just started working with FLUKA. I try to change an example from beginner's guide to have two separate RPP:
  RPP 3 -2.0 +2.0 -2.0 +2.0 -50.0 -30.0
  RPP 4 -2.0 +2.0 -2.0 +2.0 0.0 +0.5

Then I try to define two detectors as volumes of both of them.
Unfortunately I failed - always only one detector is working.
I find out that if I change the order of RPP I can make other detector works, but always only one.
I guess that I am doing a very basic mistake, probably because I do not understand something.

I am sorry to bother you with such a simple problem, but I have already spend few days trying to solve it and I am desperate now.

Attached you will find a code.

Thank you in advance!
Barbara
