I can not choose large deflection option, it is greyed out.
I am using Creo Simulate Release 4.0 and DatecodeM070
The Large deflection option is unavailable to select for a single pass contact analysis#, do I need a different licences to select this option?
Here are the errors that I faced
*** Warning: Large deformation and/or strain detected during contact analysis.
More accurate results may be obtained if 'Calculate Large Deformations' is selected.
