Large Deflection Ansys: Solving w/o Large Deflection?

[Mohamed_Wael]

What happens if I turned off large deflection in a simulation which has large deflection in Ansys workbench ? should the solution be totally wrong ? will it fail to solve ?

Here is a good overview of the large deflection option in ANSYS:http://www.padtinc.com/blog/the-focus/to-use-large-deflection-or-not-that-is-the-question

In simple terms the inclusion of large deflection means that ANSYS accounts for changes in stiffness due to changes in shape of the parts you are simulating. The classic case to consider is the loaded fishing rod.
