ADBoundaryFlux3EqnBC

Boundary conditions for the 1-D, 1-phase, variable-area Euler equations

The boundary conditions retrieves the flux from an ADBoundaryFluxBase-derived user object, such as the ADBoundaryFlux3EqnFreeOutflow.

The heat flux contribution to the residual RiR_i for the weak form of the energy equation is computed as:

Ri=(ψi,Φeqnn)ψi,R_i = (\psi_i, \Phi_{eqn} * \vec{n}) \quad \forall \psi_i,

where ψi\psi_i are the test functions, Φeqn\Phi_{eqn} the flux for the equation considered, and n\vec{n} the local normal.

commentnote

In THM, most boundary conditions are added automatically by components. This boundary condition is created by FlowBoundary1Phase-derived components, such as the InletDensityVelocity1Phase boundary component.
