Detailed Description

Spatial Transformation for cell or universe.

Transformations allow users to define cells in a local coordinate and apply a translation and/or rotation. In MCNP, this is done via TR and TRCL cards ; but the possibility of MCNP for such transformation is much more complete than the one implemented here:

• user can use TRCL card on a "standard" cell to apply the transformation
• user can use Like n but TRCL way to define cell a cell identical to cell n but with a geometrical transformation applied
• user can define transformation to universe in LatticeCell fill with universe numbers In Serpent transformations only apply to universes ; this mean that the cell (i.e. the Shape) should have a universe and the transformation will applies to ALL cells with that universe number.
