Integrating diverse CFD tools

"[A] lot of acceptance within the scientific community"

This short paper from DLR discusses something every CFD user has experienced: the evolution of CFD from being a stand-alone discipline to being a part of a complex multi-disciplinary simulation task. The 2010 paper features Python serving as the glue between diverse software components. Python's utility for CFD covers much more, of course, as discussed here, here, and here.

Revisiting Output-Based Mesh Adaptation

Some errors are more important to different engineering metrics than others

Grid adaptation can mean different things: with overset grids, for instance, it can mean modifying the grid to improve overlap. More common use involves error estimates to automatically modify critical regions without a priori knowledge of the solution. This article is from the perspective of the grid - for instance the importance of access to the geometry. Bonus resources: Onera M6 example and an adjoint-based adaptation example.

SU2 and Parallel TecIO

Writing SZL files in parallel while running on a HPC system

Tecplot has implemented parallel SZL output in SU2 using the TecIO-MPI library, as described here. Whether you prefer to download the SU2 binaries or build-from-source, use OUTPUT_FILES= (TECPLOT, SURFACE_TECPLOT) in your SU2 config file to get .szplt files that are faster to write, faster to read, smaller in size ... why wait?
