| Foam::fv::zeroDimensionalMassSource | |
| Description | |
| This fvModel applies a mass source to the continuity equation and to all | |
| field equations, in a zero-dimensional case. Correction is made to account | |
| for the mass that exits the domain due to expansion in space, so that the | |
| model correctly applies a total mass flow rate. | |
| This model requires a corresponding field source to be specified for all | |
| solved-for fields. | |
| This model will write out additional fields, zeroDimensionalMassSource:m | |
| and zeroDimensionalMassSource:factor. The zeroDimensionalMassSource:m field | |
| is the total accumulated mass; the sum of the starting mass, plus all mass | |
| added by models of this type. This may differ from the actual current mass | |
| (= rho*V) within the zero-dimensional cell if pressure or density | |
| constraints are being used. The zeroDimensionalMassSource:factor field is | |
| the ratio between the current mass or volume and the total accumulated mass | |
| or volume. | |
| Usage | |
| Example usage: | |
| \verbatim | |
| zeroDimensionalMassSource | |
| { | |
| type zeroDimensionalMassSource; | |
| massFlowRate 1e-4; | |
| } | |
| \endverbatim | |
