The interface for fvModels has been modified to improve its application
to "proxy" equations. That is, equations that are not straightforward
statements of conservation laws in OpenFOAM's usual convention.
A standard conservation law typically takes the following form:
fvMatrix<scalar> psiEqn
(
fvm::ddt(alpha, rho, psi)
+ <fluxes>
==
<sources>
);
A proxy equation, on the other hand, may be a derivation or
rearrangement of a law like this, and may be linearised in terms of a
different variable.
The pressure equation is the most common example of a proxy equation. It
represents a statement of the conservation of volume or mass, but it is
a rearrangement of the original continuity equation, and it has been
linearised in terms of a different variable; the pressure. Another
example is that in the pre-predictor of a VoF solver the
phase-continuity equation is constructed, but it is linearised in terms
of volume fraction rather than density.
In these situations, fvModels sources are now applied by calling:
fvModels().sourceProxy(<conserved-fields ...>, <equation-field>)
Where <conserved-fields ...> are (alpha, rho, psi), (rho, psi), just
(psi), or are omitted entirely (for volume continuity), and the
<equation-field> is the field associated with the proxy equation. This
produces a source term identical in value to the following call:
fvModels().source(<conserved-fields ...>)
It is only the linearisation in terms of <equation-field> that differs
between these two calls.
This change permits much greater flexibility in the handling of mass and
volume sources than the previous name-based system did. All the relevant
fields are available, dimensions can be used in the logic to determine
what sources are being constructed, and sources relating to a given
conservation law all share the same function.
This commit adds the functionality for injection-type sources in the
compressibleVoF solver. A following commit will add a volume source
model for use in incompressible solvers.
