Ocean pressure field problem

luisao · May 11, 2017, 03:04

Hi everyone,

I am working on simulation in the ocean. I would like to have a bubble to rise from 100 depth. I succeed doing this with the gravity field and the intersticial tension between air and water.

My problem is about my pressure field. I would like to have, for my water and my bubble, a pressure of 1 bar at the surface and, gradually, a pressure of 10 bars at 100 depth.
I thought the gravity field would have done that.. (with the definition of the based pressure at the surface.)

The pressure is important in my case because my bubble has a diameter of 20m.

I can specify my demand if it's needed.
I would like to thank you in advance for your help.

I finally found the problem.
You just have to activate the Operating density on the Operating Condition menu.
