Hi,

I thought that I solved the first problem :D but with a p_rgh of 2 bar at the inlet its not working anymore.

Hmmm ... I am out of mind and it is so a simple geometry... hmmm :(

Hi,

as I thought everything is correct!

phase1 = water; phase2 = air.

Hi,

well :D I do not have a look at that file since now. I copied the tutorial of the compressibleInterFoam solver. I thought that there is water and air included?

I will have a look at that...

Hi, initialValues: p = 1e5...

Hi,

initialValues:

p = 1e5 (boundary = calculated)
p_rgh = 1e5
U = (0 0 0)
alphaWater = 0 (boundary = ZeroGradient for the wall and inlet = fixedValue = 1)

Hi all,

well my first quess was to set U to pressureInletVelocity and p to fixedValue like you mentioned.

But it is not working. The simulations is total unphysical and I got an Floating Point...

Hi,

okay the solver is running.

But I am not sure how I should set the BC for the inlet?

As I mentioned in the first post, the water should go inside with 2 bar while the air is with 1...
