Software The CFD Process Preprocessing is the first step in building and analyzing a flow model. Third-party preprocessing tools can also be used. After preprocessing, the CFD solver does the calculations and produces the results. Postprocessing is the final step in CFD analysis, and involves organization and interpretation of the data and images.
All Fluent software includes full postprocessing capabilities.
Third-party postprocessors can also be used. Airpak is for ventilation system design, and MixSim is for mixing applications.
