What is it about?
Numerical oscillations occurs in the convection dominated problems. Upwinding schemes are suggested to overcome this problem by modifying the Galerkin weighing functions. We have found a new and a robust way to tackle this problem without modifying the original Galerkin scheme for a moving condcutor problem. This is achieved through the pole-zero cancellation technique.
