https://forums.autodesk.com/t5/cfd-forum/reducing-computational-costs-sst-turbulence-model/m-p/9637192#M4777 <P>I am modeling the external aerodynamics of a class 8 vehicle (in other words, a semi-truck). In order to achieve a y+ value less than 1 for accurate results with the SST Turbulence Model, I have refined the boundary layer that exponentially increases my computational costs. Currently, my simulations use 25+ million fluid elements. Any insight or tips on how to reduce this element count would be greatly appreciated</P> Wed, 15 Jul 2020 15:44:23 GMT Anonymous 2020-07-15T15:44:23Z https://forums.autodesk.com/t5/cfd-forum/reducing-computational-costs-sst-turbulence-model/m-p/9637192#M4777 <P>I am modeling the external aerodynamics of a class 8 vehicle (in other words, a semi-truck).
