Angular limits in R-Phi-Z USRBIN scoring not displayed in formatted ascii file

Dear All,

I’m running the following test geometry scoring r-phi-z on FLUKA4-3.4

Although I have set phi limits, they are not displayed in the formatted .bnn file.
What is the reason for this? Am I doing something wrong?

Cheers, Peter

You didn’t, since you cannot (in fact, why should you?): they are pre-defined as -pi and pi. You can set the number of phi bins (over the aforementioned interval) and move the cylindrical mesh axis (which is what you actually did, shifting it from the z-axis to a parallel axis of coordinates x = 1.17 cm, y = 2.54 cm).

Thankyou very much. It seems I didn’t understand the USRBIN card correctly.

Actually apologies - this was a fault that was introduced before Peter started. It was to make a quick system to observe values at particular coordinates. That was to answer ‘ why’ but the system is clear and of course there’s other ways to handle the requirement so thank you for resolving.
