Designs are released for the front wing is particularly importantmanufacture only when results from because the rest of the car depends onthe wind tunnel match those from that; yet CFD has been rather poor atsimulation.capturing the wake structure at the front of the car. In accordance with Formula One regulations, the wind tunnel car is a However, Siemens PLM Software60% scale model. Because of the fast introduced a turbulence model withintesting cycle and shape complexity, the latest enhancements for Simcentermost wind tunnel model parts are STAR-CCM+ and now we can look at all the vortices shed off the front, side and rear and clearly see how these react with the field downstream.The CFD team aims to calculate and recalculate design changes within a few hours so that clear information is available for designers.Our simulation pipeline is very simple, says Cusdin. Other CFD software requires extensive coding, but we only write code for each new set of environmental parameters.This is the unique advantage of Simcenter STAR-CCM+ and it means that we can create templates for the design team.65'
