Re: Slip-free and pressure corner boundary condition

[jb]

Hi Albert,

Ok, that is good to know. Do you have an idea when the fixed slip boundary will become available? Is this fix something I can already implement?
(I should mention that when I used the slip boundary I manually set the normals.)

The results with a bounce-back look correct to me: https://ibb.co/gfwgMm
I think that the effects in the left corners are a logical result of using two different prescribed velocities in those edges (inlet and no-slip). I guess I should either use a pressure driven inlet/outlet (With a simple try this seemed to work at first, although eventually the simulation crashed, I will look more into it.) or prescribe a Poisseuile velocity profile like in the provided example ‘Cylinder3D’.

Thanks for your help,
Juliaan
