Hello,

i'm modelling two rotating discs sitting in a water tank. I want to introduce a second phase (air) via this discs. However if i define my discs as air inlet boundaries, tangentional velocity option as in wall boundary is no longer available. Is there a possibility to do rotating velocity inlet boundaries?

thanks for tips!

if you go to physics values under your velocity inlet you can switch the method to be Table XYZ, then load in a table that has the correct velocity components in 3 columns for various points on your inlet. This will require a little math, but is very doable.
