How To Define Hydrostatic Pressure On A Part In ANSYS Mechanical(Illustrated Expression)

In this article, we will show you the how to define hyrostatic pressure on a part surface in ANSYS Mechanical. Hydrostatic pressure is very important phenomenon for various kinds of mechanical applications such as bridge piers. So correct definition of Hydrostatic pressure is very important in engineering systems. Also hyrostatic pressure is a boundry condition in finite element analysis. So correct definition hydrostatic pressure is very important to obtain realistic results from finite element analysis.

How To Insert Hydrostatic Pressure To Parts In ANSYS Mechanical?

Click on hydrostatic pressure.

To assign hydrostatic pressure to a part in ANSYS, you need to open the ANSYS Mechanical from Workbench. In the ANSYS Mechanical interface, right click on analysis system(Static Structural in this example). Hover your mouse on Insert tab as shown by blue box then click on Hydrostatic Pressure from the opened list as shown by blue arrow.

You can only select faces r surfaces for hydrostatic pressure in ANSYS Mechanical.

You can select the face that hydrostatic force will be applied from the geometry tab as shown by blue box above. As you can see with blue arrow above, you can only select faces or surfaces of the parts in ANSYS Mechanical. This is because that the pressure application needs a geometric area in physical means.

Select face or faces of a geometry.

Select your face of the geometry that Hydrostatic pressue will be applied as shown by blue arrow. Then click on Apply button in ANSYS Mechanical.

Enter the density and acceleration.

You need to enter the fluid density that touches to your parts surface as shown in red box above. Then you can enter the hydrostatic acceleration of this fluid as components or vectors as shown by blue box above. The program will compute the hydrostatic pressure according to these values that you entered.

Enter your acceleration values.

For example we entered acceleration values to X, Y and Z coordinates 3, 5 and 7 m/s^2 respectively as shown in blue box above. Also you can see the result of these values as shown by blue arrow above in ANSYS Mechanical.

Also you can define your acceleration value in ANSYS Mechanical by Vector. You need to enter your acceleration value and you need to select a vector for it in Vector method.

The defining Hydrostatic Pressure is like that in ANSYS Mechanical.
