Dear Luigi,

Thank you for your prompt reply. Please see attached my original input file and a rough changed at an angle. My beam dump

is in the plane I am plotting and it is visible when I plot it with limited dimensions, excluding room and walls.

My revised beam dump is in one corner at the bottom of a room and is inclined at an angle and beam is at the opposite corner at the top (

as shown in the attached diagram , blue portion is beam dump, sandwiched in the concrete in brown color).

I think I need to include Hx, Hy, Hz, at an equal angle, to describe exact position of dump?

Best regards,

Dear Zafar,

about your first point, for sure it is possible to draw the boundaries of the target in the plot, provided that the target lies in the plane you are plotting.
If you post you input file, we could make a check.

Concerning the second point, I can suggest you two possibilities:
1) you can define an RCC with any possible orientation (see manual section As an example
RCC cyl 0.0 0.0 0.0 0.0 -70.71067811865 70.710678118655 50.
is a cylinder 100 cm long and of 50 cm radius, rotated by 45 degrees around the x-axis

2) use the directive “start_transform”, refer to the manual section

Best regards,

Dear FLUKA experts and users,

I have two simple points to clarify which I am not tracing out.

Firstly, I have an electron beam dump in a room and I want to see dose rate around the beam dump and
around the walls. In the dose rate contour plots, one is attached with this email, I am seeing the boundaries'/dimensions
 of the wall and not seeing the boundaries/dimensions of the beam dump, although the beam dump is not so small, about
50 cm radius and 100 cm long. I have seen a few presentations , like from Anna Ferrari, etc where they have same type of
plots and dimensions can be clearly seen. How can I improve my contour plots?

Secondly, I am using RCC to define cylinders along z-axis , etc. If cylinders are not along z-axis but making an angle say 45
degree with z-axis then can it is possible using RCC or any other option to rotate cylinders? Similar is the case for beam direction,
 at 45 degree angle with z-axis.

If any body can comment on these, thank you in advance.

Best regards,
Zafar Yasin
