Description:
It seems apparent that for inviscid calculations the differences between the explicit and implicit boundary formulations tested are far smaller than anticipated. New work should focus on understanding of how the convergence rate is limited or affected by boundary formulations. Since the inflow/outflow boundary treatments tested were simple extrapolations, it may be the case that treatments more closely representing the differential equations will prove to have superior convergence properties. However, several such improved boundary treatments were attempted with disappointing results.
