Pressures
A pressure is a distributed force that acts perpendicular to every point along the face. Use the Apply Pressure tool on the Loads icon to apply a pressure.

Pressures typically arise from gases or liquids pressing on a face and can act in either the inward or outward direction on a solid. To apply a distributed force to a face that acts in a single uniform direction across the entire face, use a force instead of a pressure.

Apply a Pressure
Select the Pressure tool, click on a face, and enter a magnitude.
-
On the Structure ribbon, select the Pressure tool on
the Loads icon.
Tip: To find and open a tool, press Ctrl+F. For more information, see Find and Search for Tools. - Click on the desired face. Hold the Ctrl key to apply the pressure to multiple features on the same part.
-
Enter the magnitude of the pressure in the text field on the microdialog and
press Enter.
-
Click the
icon to reverse the direction of the pressure.
-
Use the options on the microdialog to change the
alignment of the pressure, using one of the following methods:
- Use the X, Y, Z buttons to align the pressure to the X, Y, or Z axis. Click a second time to reverse the direction.
- Use the Move tool on the microdialog.
- Right-click and mouse through the check mark to exit, or double-right-click.
- When created, pressures are automatically assigned to the current load case.
- You can also apply a force as a pressure if all you know is the magnitude of the force. Simply create a pressure and enter the magnitude in force units.
- Use the Property Editor to change the name, magnitude, direction, and appearance of the pressure.
Microdialog Options
Double-click a pressure to enter editing mode, which opens the Pressure microdialog.
![]() |
Change the direction of the pressure. |
![]() |
Enter a magnitude for the pressure. The magnitude of a pressure is specified in terms of force per unit area. |
![]() |
Rotate the pressure using the Move tool. |
![]() |
Align the pressure to the x-, y-, or z-axis. |
![]() |
Align the pressure normal (perpendicular) to the face. |
![]() |
Click to orient the pressure by entering component vectors for x, y, and z. (For example, entering 1, 0, 0 would orient it in the positive x direction.) |
Pressure Mapping
Use the Pressure Mapping table to enter the position and magnitude of your pressure data. You can also import this data in .csv format
You can apply a non-uniform distributed pressure using an option in the microdialog.

Selecting the Non-Uniform Pressure option opens the Pressure Mapping table, where you can enter the position and magnitude of your pressure data. You can also import this data in .csv format.
