Crucial part of CFD involve three aspects :<br /> * 1. Differencing schemes - representation of individual derivatives <br /> * 2. Matrix inversion - iterative solution of individual equations<br /> * 3. Algorithms - SIMPLE, PISO, Pimple (etc)<br /> <br /> Numerical methods for all these need to be speci�ed. Scheme parameters typically also need to be provided. 1. is in fvSchemes; 2, 3 in fvSolution.
