All things being equal, CFD practitioners prefer to use hexahedral mesh cells in the boundary layer for the improved robustness and accuracy they bring to the flow solver. Traditionally, a hex grid would be created using a structured grid technique … Continue reading
This week’s CFD news, while formatted differently, includes all the usual suspects including an article about whether CAD files are going the way of the dodo. There’s a tasty CFD application involving gelato. The application case study about cars driving … Continue reading
The Y+ Calculator app is a handy tool for calculating the grid spacing to achieve a target y+ value for viscous computational fluid dynamics (CFD) computations. Simply specify the flow conditions, the desired y+ value, and compute your grid spacing. … Continue reading
Something was happening early in 2020 that distracted me from writing my usual article about CFD in AIAA’s annual Year in Review issue of Aerospace America. What was it? Having trouble remembering. Hmm… Oh, right – that pandemic thing. Regardless, … Continue reading
