FVNeumannBC
Neumann boundary condition for finite volume method.
Overview
A FVNeumannBC may be used to specify a diffusive or an advective flux. For example, to specify a flux boundary condition in the following diffusion problem, a FVNeumannBC with a constant value of may be used.
where is the domain, is its boundary, and is a point on the domain or its boundary. In this case, a FVNeumannBC object is used to impose the condition (2) on the subset of the boundary denoted by . In this case, the value field corresponds to the constant , and the user must define one or more sidesets corresponding to the boundary to pass to the boundary argument. For this particular problem, an additional boundary condition, for example a FVDirichletBC as in (3) would also be necessary to remove the nullspace.
Likewise, to specify an advective flux of constant value in a 1D advection problem with an advective velocity :
The advective flux, the value to specify to the boundary condition (2), is .
Modeling a multi-dimensional problem will require a FVNeumannBC per component.
commentnote
When using the Navier Stokes module, FVNeumannBC may not be available for use with velocity and pressure, as additional information is required on either the gradient or direction of these variables to model fully developed flow for example. Specific boundary conditions are provided, see for example INSFVOutletPressureBC.
