Rotate the voxel geometry

Dear fluka experts,
I want to rotate the voxel geometry in flair by using transform card, but there is no change. So can voxel geometry not be rotated? What should I do to change the direction for my voxel geometry? Thanks in advance!

Best regards,

Xiaoman

Hi Xiaoman

you need to create a transformation with the ROT-DEFI card and apply it to the Trans: field of the Voxel like it is shown below
