Hi (Jan, Vaclav),

If I understand correctly (looking at scripts), Cell::trsf is currently
used to define the initial geometry of the period (e.g. applying
rotations). Is that correct? I didn't expect this usage when I
introduced it, as it was supposed to record cumulated transformations.
The annoying thing is that it is impossible to uncouple initial geometry
and material transformation in this approach. For instance, it is not
possible to have trsf=Zero for initial cells that are not an axis aligned.

My suggestion is to define the initial geometry using Hsize, instead of
refSize and trsf (the old behaviour would still be possible).
I started implementing that, but before I commit anything, did I
overlook something?

Bruno
