The objective of this project is to develop methods for reducing the degradation of numerical solutions for fluid flow problems during the refinement / derefinement process. The transition effects that arise when features (such as shocks) cross refinement interfaces will be investigated analytically and numerically using an existing adaptive mesh implementation. The issue of spurious oscillations at refinement interfaces need to be resolved for adaptive mesh refinement to be used more widely in industry.
