 41  * Fast simulation model is used in order to define where particle enters the detector
 42  * and its direction. That data is used to define the mesh used for energy scoring.
 43  * TODO To make the simulation faster, this model could be attached to a very thin layer at the
 44  * entrance to the calorimeter instead of attaching it to the volume of the detector.
