As discussed in Section 25.4.1, a number of pressure interpolation schemes are available when the pressurebased solver is used in FLUENT. For most cases the "standard'' scheme is acceptable, but some types of models may benefit from one of the other schemes:

The secondorder scheme cannot be used with porous media or porous jump.


Only PRESTO! and bodyforceweighted schemes are available for the VOF and mixture multiphase models.

Note that you will not specify the pressure interpolation scheme if you are using the Eulerian multiphase model. FLUENT will use the solution method described in Section 23.5.11 for Eulerian multiphase calculations.
