Creating Cartesian Coordinate System In ANSYS Mechanical(Illustrated Expression)

Coordinate systems are very important parameters to define boundry conditions in various analyses in ANSYS Mechanical. So definition of different coordinate systems out of Global Coordinate System is very useful tool in ANSYS Mechanical. In this article we will show how to create or define a cartesian coordinate system in ANSYS Mechanical.

How To Create A Cartesian Coordinate System In ANSYS Mechanical?

Click on ‘Coordinate System’ in ANSYS Mechanical.

To create a cartesian coordinate system in ANSYS Mechanical, right click on ‘Coordinate Systems’ tab as shown by green arrow above then hover your mouse on ‘Insert’ tab and click on ‘Coordinate System’ as shown in green box above.

Select the place of new cartesian coordinate system in ANSYS Mechanical.

Select where do you want to define your new cartesian coordinate system as shown in red box above. Then click ‘Apply’ button as shown by red arrow.

Select the principal axis of new cartesian coordinate system in ANSYS Mechanical.

At ‘Principal Axis’ section, select the principal axis such as X, Y or Z from the pop up menu. The selected principal axis will be defined according to selected Global axis that you can select as Global X Axis, Global Y Axis or Global Z Axis.

As you can see that we selected Y as principal axis, then Global X axis. The principal Y axis is oriented in same direction with Global X axis as shown by red and green arrows above. The logic is like that.

Orientate about principle axis.

The logic above is also applied in this section. We selected the Z axis in ‘Orientation Baout Principal Axis’, and selected the ‘Define By’ as Global Y Axis. The orientation of Z axis of our new cartesian coordinate system has a same orientatiın with Y axis of Global Coordinate System in ANSYS Mechanical.

You can select geometric figures as orientations.

Also you can select geometric figures as above to define the new cartesian coordinate system’s axis orientations. For exampla we seelcted ‘Define By’ as Geometry Selection, then selected the edge that shown by green arrow for orientation of Y axis as shown by red arrow above in ANSYS Mechanical.

So the definition of cartesian coordinate systems is very basic in ANSYS Mechanical.
