Default Hydrostatic pressure in 5.5

Hi,

I have a problem with the setup of a large high tank (70 meter) which is filled with water.

I have set the hydrostatic pressure within the tank since it is fill with water, but has no free surface.

As far as I can see the only way to do this is to use the free surface model, but the problem has no free surface.

Does any on has a hints ?

Thanks a lot.

Regards

Jens

Hi Jens,

There was a long discussion of this topic sometime last year on the forum. See this thread for explanations:

Hi

Thanks for the reply. But I still think the answer are bit confusing, since as I understand CFX-5.5 does no include total sum of pressure only there relative pressure distribution. (So it does no have hydrostatic pressure) So in order to visulize it I have to include into CFX-Post and add it to relative pressure.

That seems strange, since there are a lot of cases where it does matter.

It this assumtion okay ?

Regards

Jens

Hi Jens,

This is no longer the case in 5.5.1. The hydrostatic pressure contribution is included in the Pressure, plus an additional vector, Buoyancy Force, is also provided.
