Deformed-mesh

Hi there,
I am trying to visualise my results showing a deformed mesh! However, when I am ticking the box to see the deformed mesh an error comes up as could be seen in the attached picture?
Any suggestions?
Kind regards
Bashar

To set the main deformation go to menu:
Window->View results…


and set the vector result to be used to deformate, and the scale.

or go to menu
View results->Deformation->your vector result
