3‐D Mesh Adaptation on Multiple Weak Discontinuities and Boundary Layers

This paper presents new developments within an anisotropic mesh adaptation methodology, made essentially by the introduction of a metric modification and a shock-filter model that allow crisp capturing of weak shocks, as well as boundary layers and wakes. Inviscid and laminar external flow tests are...

Description
Summary:This paper presents new developments within an anisotropic mesh adaptation methodology, made essentially by the introduction of a metric modification and a shock-filter model that allow crisp capturing of weak shocks, as well as boundary layers and wakes. Inviscid and laminar external flow tests are used to demonstrate the efficiency of the method.
