Large time-step transient solver for incompressible, flow using the PIMPLE (merged PISO-SIMPLE) algorithm.
Original source file pimpleFoam.C
Solver details
The solver uses the PIMPLE (merged PISO-SIMPLE) algorithm to solve the continuity equation:
![\[ \div \vec{U} = 0 \]](form_219.png)
and momentum equation:
![\[ \ddt{\vec{U}} + \div \left( \vec{U} \vec{U} \right) - \div \gvec{R} = - \grad p + \vec{S}_U \]](form_277.png)
Where:
 | = | Velocity |
 | = | Pressure |
 | = | Stress tensor |
 | = | Momentum source |
Sub-models include:
Required fields
| U | : | Velocity [m/s] |
| p | : | Kinematic pressure, p/rho [m2/s2] |
| <turbulence fields> | : | As required by user selection |
