Upon start of a simulation case, a few dynamic script files with file ending
*.rd are generated. The contain the following information:
boundingbox.rd- The names and detailed information of each volume segment actually used in the simulation run.
surfaces.rd- Information on the interconnection and boundary conditions of each volume segment.
species.rd- Molecular mass, charge and statistical weighting factor of each gaseous species actually being used in the simulation run.
load_balance.rd- Assignment of each volume segment to a CPU process.
