A boundary condition which models locally reacting boundaries is derived for the generalized parabolic equation. This formulation is valid over nonhorizontal boundary surfaces. The derived condition is discretized using Lagrange polynomials. Particular implementation schemes are discussed for nonhorizontal boundaries. Numerical results compare the accuracy of this approach with other methods that have been used with the PE. Comparison with experimental results may also be presented.
