Define pressure exerted by a fluid at equilibrium.
Hydrostatic pressure is defined as a pressure exerted by a fluid at equilibrium at
a given point within the fluid, due to the force of gravity. Hydrostatic pressure
increases in proportion to depth measured from the surface because of the increasing
weight of fluid exerting downward force from above.

On the Project Tree, open
the Analysis Workbench.

On the Analysis Workbench, click the (Hydrostatic pressure) icon.

In the modeling window, select faces to apply
hydrostatic pressure to.
 Optional:
You can select the Add tangent faces check box.

Locate the fluid surface by defining the X, Y, and Z coordinates under
Coordinates of a point at liquid surface.
Tip: You can also locate the coordinates in the modeling window using the graphical representation of the
hydrostatic pressure load. Drag the ball around the model until it is in the
desired position.

Define the Depth direction X, Y, and Z directions.

Specify units and value for Liquid density.

Specify units and value for Pressure at liquid surface.

Click OK.
The hydrostatic pressure load appears in the
Project Tree. If selected, a graphic representation
appears on the model.
Note: If a gravity direction is already defined, the depth
direction uses this existing definition. In this case, you can locate the
surfaces elevation, but not change its direction.
