Hi,
I am wondering if anybody tried to use the shroud marker as boundary condition. Can anybody explain me how to use it? What is the difference compared to Euler? Code:

I've not used this myself, but looking at the code I think the purpose of that marker it to specify a stationary shroud (in an otherwise rotating domain).
It is not a boundary condition by itself, you still need to have a Euler/Heatflux/Isothermal boundary condition for that marker. |
