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.
