My name is David and I try to rotate a custom FLUKA model for arbitrary yaw, pitch and roll angles.
I’ve implemeted this rotation in my FLUKA model using the ROT-DEF cards in combination with the transform card. Now, for a very specific angle, I get some unexpected geometry errors highlighted in FLAIR. These angle is Yaw=45 degree (TH_yaw parameter in the attached input script). For all other tested angles, no errors occured.
- I have no idea, what the reason for this error could be. Is there a problem with my geometry?
- How can I prevent such errors?
I’ve copied the problematic region to the input file “rotation_test.inp”. The three rotation parameters are TH_yaw, TH_pitch and TH_roll. As already said, the problematic angle combination is TH_yaw=45, TH_pitch=0 and TH_roll=0.

If you need more information/details or have further questions, please contact me in the personal fluka section or by e-mail (email@example.com).
Thank you very much for your support
P. S. I’ve used the newest CERN version FLUKA4-3.1 for the test simulations together with the newest FLAIR software version 3.2-1.
