Class
    Foam::fixedRhoFvPatchScalarField
 
Group
    grpInletBoundaryConditions
 
Description
    Foam::fixedRhoFvPatchScalarField
 
    This boundary condition provides a fixed density inlet condition for
    compressible solvers, where the density of calculated using:
 
    \f[
        \rho = \psi p
    \f]
 
    where
    \vartable
        p     | pressure [Pa]
        \rho  | density [kg/m3]
    \endvartable
 
 
Usage
    \table
        Property     | Description                | Required    | Default value
        p            | Pressure field name        | no          | p
        psi          | Compressibility field name | no          | thermo:psi
    \endtable
 
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            fixedRho;
    }
