Abstract: Using a couple of relatively simple python utilities, OpenFoam simpleFoam solver and Kaleidosim cloud platform, Prof. G. Boiger of ZHAW_ICP does a 20min live-demo of a work-flow that would have taken one-two full working days only six months ago: The famous OpenFoam 'Motorbike' tutorial case is modified such that relative onset flow velocity is rotated in one-hundred, 3.6 degree steps (360° in total) around the motorbiker. One-hundred individual turbulent steady-state OpenFoam simulation cases are then created automatically, uploaded and run simultaneously in the cloud using Kaleidosim (MSCC Massive Simultaneous Cloud Computing). Drag- and lift- coefficients are being calculated and evaluated for each case from parsing terminal output. One paraview image is being automatically created per simulation run in the cloud using paraview-batch-mode. Results are selectively downloaded from the cloud and paraview images are forged into one movie, rotating the view around the motorbiker along with resulting turbulent flow-field calculation.
