Dear SimScalers,
in this weeks spotlight we will have a look at fluid dynamcs simulation taking into account passive scalar transport of a truck by our PowerUser @varsey .
Introduction
The project represents the CFD simulation of a driving truck with exhaust gases coming out its exhaust pipe (CFD + Scalar Transport modelling). The CAD model of the truck has been simplified with the program SALOME.
