Class
Foam::fv::zeroDimensionalFixedPressureModel
Description
Zero-dimensional fixed pressure source. Should be used in conjunction
with the zeroDimensionalFixedPressureConstraint.
This constraint and model facilitates specification of a constant or
time-varying pressure. It adds mass source terms proportional to the error
that remains when the pressure equation is evaluated at the desired
pressure. Iteration may be necessary to converge the constraint in the case
of non-linear equations of state.
Properties are added or removed with their current value. The model
therefore represents a uniform expansion or contraction in infinite space.
Usage
Example usage:
\verbatim
{
type zeroDimensionalFixedPressure;
}
