| Abstract: | This is a tutorial video in Prof. Gernot Boiger's series on OpenFOAM and the cloud computing platform Kaleidosim. Here the focus lies on the 'EVAL' functionality within OpenFOAM v1912 (and later). Using the 'EVAL' function the user can prescribe (dynamic) boundary conditions from inside any OpenFOAM dict, based on a multitude of mathematical expressions. In this movie the 'EVAL' function is demonstrated based on an example surrounding the classical simpleFoam Motorbike tutorial case with a 'twist'. The 'twist' is about conducting a full #aerodynamic #CFD study of the #Motorbike frame, involving 360 individual simpleFoam #simulation runs simultaneously conducted within Kaleidosim #cloud platform. Thereby each run differs in that onset-airflow velocity vector as well as the entire bounding box of the simulation vicinity (wind channel) are rotated degree after degree (step size 1°) around the Motorbike, yielding 360 simulation cases. The 'EVAL' function performs the math to rotate the bounding box based on a 2D rotation matrix with respect to the angle-of-attack, while Kaleidosim's Kaleidoscope Feature conducts a parameter-study varying the angle-of-attack step-by-step. Furthermore the video contains a demonstration of how, thanks to Kaleidosim's MSCC Massive Simultaneous Cloud Computing capacity, the entire study can be completed in no more than 25min.
