Application
    pimpleTimeFoam

Description
    Large time-step transient solver for incompressible, flow using the PIMPLE
    (merged PISO-SIMPLE) algorithm.

    Turbulence modelling is generic, i.e. laminar, RAS or LES may be selected.

    Consistent formulation without time-step and relaxation dependence by Jasak
