WCNs and higher-order grids

Some of FEM’s advantages for CFD are related to the use of higher-order-polynomial interpolations. But creating higher-order grids for viscous flow is a challenge near highly curved geometric boundaries: high aspect ratio mesh cells can become inverted or suffer other quality problems. Read this article for details on how Pointwise uses weighted-condition-numbers to achieve high-quality higher-order cells that work great for CFD.
