Apply a rotation and translation to a cartesian mesh filter

Hi everybody,

I’d like to know if it is currently possible to apply both a rotation and a translation to a cartesian mesh using OpenMC. I did use in my code :

mesh = openmc.RegularMesh()
mesh.type = 'regular'
mesh.dimension = []
mesh.lower_left = []
mesh.upper_right = []

meshfilter = openmc.MeshFilter(mesh)
meshfilter.rotation = ()
meshfilter.translation = ()

This ran without any error message and gave some satisfactory results. However, when I take a look into my tallies.xml file, I can’t see any rotation or translation applied to the corresponding mesh id.
Perhaps this yielded to good results because the rotation and translation applied were very small.
OpenMC class MeshFilter (openmc.MeshFilter — OpenMC Documentation) shows that translation can be applied, but there’s nothing about rotation.

Does anyone have a clue ?

Thanks in advance,
Marino
