Calculation will run with almost 2-fold (Dual Core) or 4-fold (Quad-Core) the speed.
Calculation will run up to 16-fold the speed. (Requires multiple networked sufficient PCs; Special Installation knowledge required.)

In this form receptor points can be summarized to collectives. Those collectives will be illustrated as evaluation areas.
For each receptor point collective one pre-pollution can be set. If no settings for pre-pollution were done, the program will calculate with the settings from the form "Global parameters".
Collective number /number of the evaluation area.
Each receptor point collective can be related to up to nine receptor points.
