RE: tracking or geometry problem?

Dear Vasilis,

Thank you very much for your answer. In fact I have already implemented
it and runs smoothly. In my case I broke the x,y,z values of my original
ROT-DEFI card, in three ROT-DEFI cards each one for x,y,z. I just hope
that no limit exist in Fluka for the number of ROT-DEFI that have the
same SDUM.

Dear Makis,

You can always break the ROT-DEFI cards into two or more cards=20
One with only the translation and a subsequent one with only the
rotation. Of course all of them should have the same SDUM or WHAT(1)

You have to remember that the order of the transformations is important.

Cheers
Vasilis

Dear Makis,

indeed you did not do anything stupid. The unfortunate problem is that
also free format cards turn out to be (unintentionally) limited to 80
characters. So your ROT-DEFI cards are not interpreted correctly.
Then, for the time being, the increaded precision allowed by the free
format has to be reserved for the WHATs actually needing it (especially
the rotation angle), without breaking the 80 character card limit.

Cheers

Francesco
