Class
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
