buoyancy-driven
 

I'm pretty to openFOAM, I would like to know how I can change (increase or reduce) the reynolds number in the buoyancy-driven case tutorial?

Any help on this would be appreciated

Thanks much

:)
well, you can change your fluid properties or change temperature difference to increase velocity

Right, thanks much for your reply. I am having some trouble with this tutorial, After giving all the parameters for the streamline plots the geometry or domain disappers, and I can't get the tracer?

not sure about what the problem would be?

Thanks,

its easy ;) you need just to click on stream traces and choose appropriate line source, if domain disappear, look whether the eye in pipeline browser is active or not :)

Right, I did it and I keep having the same problem? OpenFOAM works with staggered or collocated grids options. I've seen here that all the solvers work with collocated?

as much as i know it works with collocated solvers
