Deformation Scaling Options In ANSYS Mechanical

If there is a deformation in your analysis in ANSYS® Mechanical, sometimes it can be very hard to observe it. But sometimes, you need do some adjustments to see actual deformation. Here, we will explain to you how to adjust deformation scales in ANSYS® Mechanical.

How To Adjust Deformation Scales In ANSYS® Mechanical?

Solved model in ANSYS® Mechanical.

First of all, you need to have a solved model as above in ANSYS® Mechanical. After that, you can adjust the deformation options in ANSYS® Mechanical.

Deformation illustration options.

As you see above, there is great deformation displayed in ANSYS®. In the actual stage, there could not be deformation like that. This display of deformation is because of deformation illustration options that are shown in the green box above.

These deformation options are;

  • 0.0(Undeformed): If you choose this option, the stress and deformation rates will be shown but there is no deformation will be illustrated.
  • 1.0(True Scale): If you want to see the actual deformation of your model, you need to select this option.
  • 0.5xAuto: This is half of the Auto Scale deformation option. There is an 1xAuto, 2xAuto and 5xAuto options.

It will be more healthy to select the scale deformation as program-controlled. The program will select the deformation scale according to the analysis type and material situation.

When you are working with Modal Analysis in ANSYS® Mechanical, it will be better to adjust Auto Scale to see unreal deformations. Because in Modal Analysis, deformations that are displayed, are not the real deformations.


In Random Vibration analysis, Harmonic Response and Response Spectrum, Mechanical adjusts the deformation as zero.

If rigid bodies exist, user, define springs are exist and large deflection is on in model, it will be better to see Tru Scale deformation in ANSYS® Mechanical.


These are the general characteristics and options of deformation scaling and displaying in ANSYS® Mechanical.
