This Week in CFD – On Hiatus

This Week in CFD, the weekly blog post with all (?) of the fluids-oriented CAE news and entertainment (?) for the CFD lover, the compulsive reader, and the morbidly curious, is going on hiatus for the rest of September and should return in all its former glory (?) on October 2nd. #NotTheRona

Recap of Six Recent CFD Success Stories with a Meshing Assist

No one generates a mesh just to generate a mesh. The proof of a mesh’s suitability is successful use in a CFD simulation. That success can be predicated on many factors including the availability of a broad range of mesh types, algorithms that produce well-shaped mesh cells, a scripting language that allows the process to be automated, flexibility to integrate into your simulation process, and more. These six recent case studies demonstrate what you can do with the right mesh in applications ranging from nuclear power generation, to biomedical pumps, to fan acoustics, truck aerodynamics, and a boiler.

Use of Grand Challenge Problems to Assess Progress Toward the CFD Vision 2030

Join the AIAA’s CFD 2030 Integration Committee at SciTech 2021 this coming January for four invited talks and an extended Q&A session on formulation of grand challenge problems that would provide a basis for assessing progress toward the CFD Vision 2030.

This Week in CFD

This week’s CFD news brings some excellent reading as we head into a 3-day weekend, at least here in the U.S. It begins with a research article on undergraduate education that’s certain spark thinking if not debate. And our friends at Siemens share a lengthy and beautifully illustrated article about turbomachinery flowfields. The image shown here is an example of a gearbox lubrication simulation done with Nextflow’s recently announced SPHflow.

This Week in CFD

This week’s CFD news includes articles that pose questions about open source software. Does it have a people problem? And are people prejudiced against it? Proving that good things never get old, there’s a multi-part video series on fluid mechanics that’s as relevant today as it was in the 1960s. And if you’re looking for geometry models to 3D print, the new kid on the block is Thangs. The image shown here is a polariscope image of anisotropy in glass from an article about use of CFD to study the tempering of glass using ANSYS and OpenFOAM.
