We have run a demonstration simulation with our GPU capable CFD code DrNUM. Goal of this demonstration was to show how DrNUM could be used to efficiently simulate environmental flows.
The DrNUM CFD software was designed from scratch with massively parallel hardware in mind (e.g. GPUs). As a result it is able to perform a complex LES (large eddy simulation) on comparatively cost efficient hardware. We believe this is ideally suited for environmental fluid mechanics. It could, for example, be used to improve wind park layouts or compute pollutant transport.
Below is a small introductory video which shows an example computation for a region close to our office. It uses real terrain data which is freely available from an old radar mission done by the Space Shuttle. The terrain data has a resolution of 90 metres and the CFD mesh uses a cell size of 12 metres which results in a total mesh size of about 80 million cells. The whole simulation, as it can be seen in the video, run for approximately 20 hours on a single PC.
The DrNUM technology can bring high end CFD simulations to normal engineering projects, because it removes the need for expensive high performance hardware.
The satellite imagery we have used for the video has been retrieved from Google Earth and the map is from the OpenStreetMap project.
We are looking for partners to bring this development forward!
