How To Define Moment In ANSYS® Mechanical(Illustrated Expression)

In this article, we will show you how to define a moment to a geometric feature in ANSYS® Mechanical. In mechanical systems, moments have a very important place. Calculation and application of moments to structural systems can affect the behavior of the part or engineering system. So defining moments correctly is a very important thing for engineering systems. Also, Moment is a boundary condition in finite element methods and you know that the boundary conditions in finite element methods are a very important parameter.

In this text, you will learn about how to apply moments to parts in ANSYS® Mechanical in an effective way.


How To Define Moment On A Part In ANSYS® Mechanical?

To apply a moment to a part in ANSYS® Mechanical, you need to right-click on the analysis system(Static Structural in this example). After that, you need to hover your mouse on the Insert tab as shown by the red arrow then click on the Moment command as shown in the red box above in ANSYS® Mechanical.

You can select the geometry to apply moment on it as shown by the red arrow above. Click on the geometric feature or features then click on the Apply button in the Geometry section as shown by the red arrow in ANSYS® Mechanical.

You can define your moment value as components or as a vector as shown in the red box above in ANSYS® Mechanical. If you select Components, you need to enter your moment value as X, Y, and Z coordinates. Also, you can add your moment by selecting a vector that you enter a moment value and define a vector from the geometry.

For example, we defined the moment as shown in the red box in X, Y, and Z coordinates, and the resultant of these moment values as shown by the red arrow above in ANSYS® Mechanical.

Also, you can define moment behavior such as Rigid, Deformable, Coupled, or Beam. If you select the Beam, you need to specify a Beam diameter.


The moment application in ANSYS® Mechanical is like that.

  1. que veut dire couplé ? que se passe-t-il pour le modèle ?

    1. Hello, can you write in English so that we can fully understand what you are saying?

    How does selecting multiple faces(while applying moment), rather than a single face in the object, affect the result of the moment?

    1. You are applying the same moment value to the two faces in same time. Thus, the effect will different.
