Mesh Adaptation With Python, Pointwise and Caelus

Mesh adaptation is one of the NASA 2030 goals, and has been one of the areas of research and development by Pointwise in past case studies and webinars. Applied CCM is the distributor for Pointwise in Australia and New Zealand, and has also been developing mesh adaptation toolsets with an OpenFoam derivative Caelus. The Applied CCM mesh adaptation toolset has produced adapted meshes like the wing and store pictured. The wake past the wing, store and missile each have vorticity that refines the mesh locally via a point cloud. This would avoid having to decide where to put Pointwise source shapes, and would allow the mesh to refine based on the flow characteristics and different angle of attack.
