spc_outlet_zero_prsgrd Subroutine

public subroutine spc_outlet_zero_prsgrd(me, state, bcBuffer, globBC, levelDesc, tree, nSize, iLevel, sim_time, neigh, layout, fieldProp, varPos, nScalars, varSys, derVarPos, physics, iField, mixture)

Outlet boundary conditions with zero pressure gradient.

These boundary conditions use the neighbor cells density and velocity in the equilibrium function. It is not necessary to specify density at boundary in the lua configuration file $f = f^{eq}(\rho_{b-1},u_{b-1})$

This subroutine's interface must match the abstract interface definition boundaryRoutine in bc/mus_bc_header_module.f90 in order to be callable via fnct function pointer.
