This boundary condition provides an advective outflow condition, based on solving DDt(psi, U) = 0 at the boundary.
The standard (Euler, backward, CrankNicolson, localEuler) time schemes are supported. Additionally an optional mechanism to relax the value at the boundary to a specified far-field value is provided which is switched on by specifying the relaxation length-scale lInf
and the far-field value fieldInf
.
The flow/wave speed at the outlet is provided by the virtual function advectionSpeed() the default implementation of which requires the name of the flux field (phi) and optionally the density
(rho) if the mass-flux rather than the volumetric-flux is given.
The flow/wave speed at the outlet can be changed by deriving a specialised BC from this class and over-riding advectionSpeed() e.g. in waveTransmissiveFvPatchField the advectionSpeed() calculates and returns the flow-speed plus the acoustic wave speed creating an acoustic wave transmissive boundary condition.
Patch usage
Property | Description | Required | Default value |
---|---|---|---|
phi | flux field name | no | phi |
rho | density field name | no | rho |
fieldInf | value of field beyond patch | no | |
lInf | distance beyond patch for fieldInf | no |
Example of the boundary condition specification:
myPatch { type advective; phi phi; }
lInf
is specified, fieldInf
will be required; rho
is only required in the case of a mass-based flux.Definition at line 118 of file advectiveFvPatchField.H.
