Dear FLUKA experts,
Recently, I was doing a simulation of a flowing target (similar to water in a pipe). I know that flow is almost impossible to realize in FLUKA. So I came up with two equivalent methods. The first is to move the source and the second is to move the target. For the moving source, my idea is to irradiate for a certain period of time ( 1 second, or even less), then the source moves (translates or rotates), then continues to be irradiated, then continues to move, and continues to be irradiated. If the time interval is right, I think it could also be considered an equivalent flow simulation. Of course, the second idea is the same principle as the first, except that the moving is the target. So I have a question for the FLUKA experts: Is it possible to realize the two ideas in FLUKA. That is, the movement of the source (irradiation-movement-irradiation-movement, of course it would be nice to be able to move while irradiating) and the movement of the target. Of course I’m hoping for automatic movement, not manual movement. I know the above process I can realize manually, like setting the position of the source (target) in the first .inp file, then changing the position in the second .inp, then the third, fourth… The nth. This method is too much work. I also see some commands (like translat\transform), but these are only suitable for geometry creation, not for irradiation-movement process.
So I would like to ask the FLUKA experts.
Thank you very much for your help and answer! Looking forward to your reply. Wish you the best of luck in everything.

Dear @linjunze,
Please check the previous topic where a similar question was raised:
It contains instructions about moving your source and scoring results depending on time.
Let me know if you will have further questions on this topic.
