CFD with OpenFOAM

Saturday, September 26, 2009

Some details and text on the Computational Fluid Dynamics simulations that mostly Jari has been doing lately. They are done with the open-source software package OpenFOAM, which is of course free to download and use. We run it under Ubuntu, and use fairly affordable 4-core machines with 8 Gb of RAM. You start with a [...]

Downwind IOM CFD

Friday, September 25, 2009

Update: video removed and replaced with this one containing more awesomeness: http://www.youtube.com/watch?v=c33qpPHd73E An IOM boat+rig in the digital wind-tunnel sailing downwind. The plan is to run a few of these and compare with actual data. Available in HQ on youtube, remember to turn the sound up!

Colorful Fluid Dynamics

Monday, September 21, 2009

Jari has put quite a bit of time and effort into learning to use the OpenFOAM open-source CFD package. It's maybe not as polished and pretty as Comsol or Ansys or any of the other 10+ keur costing commercial packages, but it seems OpenFOAM has all the same solvers and physics models and is able [...]

OpenFOAM 1.5 on Ubuntu 8.10

Saturday, April 11, 2009

Although we have a general idea of how low Reynolds number foils, bulbs, and rudders should look like, we thought it would be fun to do some Colorful Fluid Dynamics to test different airfoils and configurations. It's likely that we will pick a well-known airfoil for the first set of foils and bulb for the [...]
