Description

The uniformTotalPressure is a boundary condition that provides provides a time-varying form of the uniform total pressure boundary condition totalPressure.

Usage

The condition requires entries in both the boundary and field files.

Boundary file 

<patchName>
{
    type            patch;
    ...
}

Field file 

<patchName>
{
    // Mandatory entries
    type            uniformTotalPressure;
    p0              <Function1<scalar>>;

    // Optional entries
    U               <word>;
    psi             <word>;
    rho             <word>;
    phi             <word>;

    // Conditional entries

        // if 'psi' is not 'none'
        gamma       <scalar>;

    // Inherited entries;
    ...
}

where:

Property Description Type Required Default
type Type name: uniformTotalPressure word yes -
p0 Total pressure field Function1<scalar> yes -
U Name of velocity field word no U
psi Name of compressibility field word no psi
phi Name of flux field word no phi
rho Name of density field word no rho
gamma Heat-capacity ratio scalar conditional 1

The inherited entries are elaborated in:

  • fixedValueFvPatchField.H
  • Function1.H
