pressure and initial condition

hossein_sml · March 22, 2016, 12:17

Hi
I am trying to simulate a close container which contains water and also simulating free surface and sloshing

I have faced very strange problem.
Although i have defined initial static pressure of water by ccl. [below image], when i check pressure in CFD-Post (in t=0s) the pressure distribution all over the container is constant and equal to zero.
Also after progressing time the pressure is not changing in all over the cube!

why it is happening? Any suggestion?

You are showing the expression, but not the CCL where it is used.

Are you certain the expression is used in the correct place ? There is domain initialization, and there is global initialization. Which of the two are you using ?

Hope the above helps,

I have set it in global setting.
Also i tried to set initial condition in domain initialization.
nothing changed and the result is same.

Can you show your CCL (command language) ?
