How To Insert A Pressure To A Part In ANSYS Mechanical(Illustrated Explanation)

In this article of Mechanical Base, we will show you how to assign or define a pressure to a feature of a part in ANSYS Mechanical. As you know from engineering pressure is a very major variable in engineering problems. Definition of pressure values in engineering problems is very important. In finite element analysis, pressure variable is also very important because a pressure value on a part that will be analysed is a boundry condition. As you know from the finite element analysis, the correct definitions of boundry conditions are very important to obtain very realistic and correct analyses.


So you will learn hw to define pressure to a parts various features such as faces in ANSYS Mechanical.

How To Define A Pressure On A Part In ANSYS Mechanical?

Select pressure from the list above in ANSYS Mechanical.

First of all you need to open the ANSYS Mechanical interface to assign pressure values to parts. Right click on the analysis system in ANSYS Mechanical interface(Static Structural in this example). Hover your Mouse on the Insert section as shown by red arrow above then click on Pressure as shown by red box in ANSYS Mechanical.

Select faces of a feature to assign pressure in ANSYS Mechanical.

To define a pressure, you can only select faces or surfaces of the parts in ANSYS Mechanical as shown by red arrow. Because you need a geometric area to define pressure in physical mean. Geometry selection for pressure, you need to activate geometry tab as shown by red box above then you can select a face or surface of a part in ANSYS Mechanical.

Select your faces then click apply.

After the selection of faces or surfaces of parts in ANSYS Mechanical, clck on Apply button in Geometry tab as shown by blue arrow above.

Select components, vector or normal to for pressure assignment

As you can see above, you can assign your pressure as components, vector or normal to in ANSYS Mechanical. If you select components, you need to enter X, Y and Z values of your pressure. If you select vectors, you enter a pressure value then you select a vector to define the direction of the pressure. Normal to directly applies your pressure value to the parts surface that selected in ANSYS Mechanical.

Enter your pressure value.

We selected components method to define our pressure. We entered 500 Pa value of pressure to each X, Y and Z coordinates as shown by blue box above. You can see the result of pressure as shown by blue arrow.

The application of pressure  to a part is very basic like that in ANSYS Mechanical.
