In this article, we will show how to define pressure on different entities in ANSYS that changes with time. Defining pressure according to time on a tabular basis is very easy in ANSYS® Mechanical. Also, Pressure is a boundary condition in FEA which makes the correctness very important for healthy analysis. So you will see that defining pressure that changes with time in ANSYS is very simple.

How to Define a Pressure that Changes with Time in ANSYS Mechanical?
Firstly, you need to open the ANSYS Mechanical interface. And then, assign pressure values that change with time 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 the red arrow above. After that click on Pressure as shown by the red box in ANSYS Mechanical.
To define pressure, select faces or surfaces of the parts in ANSYS Mechanical as the red arrow. Because you need a geometric area to define pressure that changes with time in the physical mean. For geometry selection for the pressure, you need to activate the geometry tab as shown by the red box above. And then, you can select a face or surface of a part in ANSYS Mechanical.
After selecting entities of parts, click on the Apply button as the red arrow above. This is the first step to defining pressure that changes with time in ANSYS.
Define the Pressure Values as Tabular
Select one of the defining methods from the Define By tab around; Components, Vector, or Normal To. In this example, we selected Components. After that, click on the little pop-up menu as shown by the red arrow above. And then click on the Tabular(Time) option for it. You can define pressures that change with time in ANSYS.
Do the same thing that shown the former step for each X, Y, and Z component as the red box above in ANSYS.
After opening the Tabular Data option for whole coordinates, you can add time rows by entering a time to the last row as shown by the red arrow. And then press Enter from your keyboard to define pressure values for it. And you can enter pressure values for every coordinate in every period as shown in the red box above.
Conclusion
Definition of various pressure values in changing time in ANSYS Mechanical is easy like that. You can build real physical conditions that change with time in ANSYS Mechanical with this technique.
