It is based on a best fit technique, where the original geometry and the deformed geometry are overlayed in such a way that they best fit together, or based on a defined anchor plane. This can be defined using .
If the deflection values are quite small, you can magnify the display of the deflections, either in all axis directions or a selected direction only, using the Scale factor settings on the Deflection tab of the Plot Properties dialog. Deflection results can also be animated using the animation tools. The animation illustrates the change in shape of the part from the undeflected geometry (scale factor = 0) to the final deflected geometry using the specified scale factor. The component deflection plots are useful for assessing the amount of deformation in a specific direction.
The tool is particularly useful for deflection plots as it shows the coordinates of selected nodes before and after deformation and the distance between two successively selected nodes, also before and after deformation.
A warp analysis with the option activated outputs not only the total deflection results but also breaks down the total deflections according to defined contributors to warpage: differential shrinkage, orientation effects and differential cooling. Midplane and Dual Domain analyses can also display warpage due to corner effects. The contributor with the largest deflection values can be regarded as the dominant cause of warpage. Having identified the dominant cause of warpage, specific measures can then be taken to attempt to reduce the overall warpage based on the particular cause.
The deflection of specific sections of the part can be investigated.
