Hi Klaus, 

I can upload the movie on youtube soon. How can I add it to the wiki after ? 

I made one very basic script to apply buoyancy to three particles of different densities. I also made a "fluidized bed" test case, which is quite rough but looks ok. It gives an idea of what could be done more rigourously, and helps to get familiar with the discrete random walk fluctuation model included inside HydroForceEngine. You need to use the last version from the source code to make this last two scripts work, I made some small modifications in the same time. 

By the way, it may look surprising but I was not aware of the presence of this example folder which contains a lot of informations about other developments. I think there is no obvious link to this folder/examples scripts on the yade website (at least I didn't find one), maybe it would be nice to highlight it (at the end of the tutorial for example). 

Best,

Hi Raphael,

thanks for the script (haven't been able to test it yet) and the great movie. 
Are you going to upload it on youtube? I think it should be added to fluid-
solid coupling part even if you have to impose the fluid part at this stage.

BTW, do you have a some more simpler example as well (maybe constant flow, or 
buoyancy only)? I came across this [1] but when I tried the script it was not 
working.

Someone here asked me if your engine can be used for simulation fluidised beds. 
That should work, right?

Cheers
Klaus
