Large Deflection is in the same place in 18.2 as it is in 19.1 but it is only there when you are in an analysis system that allows large deflection.


Some analysis systems are strictly linear, such as Modal or Harmonic Response, and don't allow large deflection so that option is removed from the list of Solver Controls.


Take a look in a Static Structural analysis system to find that option.
