Tutorial on OpenFOAM & kaleidosim : computational parameter study of 300 cases in 25 min with kaleidoscope feature

YouTubeThis is the second video (see first one here: https://youtu.be/6T08Li7gVqE ) about introducing the Kaleidoscope Feature within the Kaleidosim cloud platform: Prof. G. Boiger of ZHAW/ICP uses OpenFOAM's Motorbike tutorial case in simpleFoam mode to demonstrate. This time a very large computational parameter study involving the RAS turbulence model parameters 'turbulent kinetic energy' and 'omega', is conducted based on just one single base case. The base case is uploaded to the cloud and multiplied within seconds to yield not less than 300 individual OpenFOAM simulation cases. All cases are then computed simultaneously in the cloud (MSCC Massive Simultaneous Cloud Computing) and the entire study is completed in only about 25min. Regarding post processing: Paraview screenshots are being automatically created per simulation run in the cloud using Paraview-Batch-Mode via a prepared #Python script that was uploaded along with the OpenFOAM case (for 'how to' see also: https://youtu.be/EzmkmrDnu0Y ). Finally (visualised) results can be selectively downloaded from the cloud using the Katana File Downloader function
