Description:The name of the variable that this boundary condition applies to
LinearFVExtrapolatedPressureBC
Description
This boundary condition is created for pressure variables in the pressure Poisson equation. It behaves just like a LinearFVAdvectionDiffusionExtrapolatedBC but its response depends on the usage:
- When it is used for the computation of gradients, the user can prescribe two-term extrapolation to the boundary faces to increase accuracy. - When it is used for building the pressure Poisson equation, it assumes a one-term expansion. The reason behind this is that for cases when the pressure needs to be pinned, adding boundary-related terms to the right hand side of the system will emulate a boundary source which yields unphysical results.
