I would like to ask about Total Deformation in Static Structural. I'm doing an analysis on a wing structure of an aircraft model. As seen in the pictures below, I've applied 9.81N downward force at the surface of both propellers attached to a carbon fiber pylon and there are also several fixed supports. The problem now is that the maximum deformation obtained is 0.2 mm which is non-logical as the pylon should deform at least 10 mm or around that range. Is there any way to increase the total deformation exerted to the pylon without any major modifications? Thank you.
Below are the picture of total deformation with the force and fixed support set for the analysis.

Will you please check if the large deflection is on or not? which type of element have you taken to model the propeller attached? Will you please check the force value that you have applied?

Will you please let me know the length and diameter of the propeller, and will you please verify the contact that you have used? How are you sure about the 10 mm deflection in the structural steel propeller? How is the propeller connected to the carbon fiber pylon? Will you please show the backward view of the model?

In the geometry is the mount quad for the propeller and below are the dimensions of the mount quad (Diameter propeller = 13 mm). I'm not sure about the contact used for it.
I'm expecting the deflection to be more than 1 mm as 0.2 mm deformation is not realistic for me. 5 mm deformation should be fine (I can also consider changing the material for the propeller).
The mount quad will be screw together with its pair to hold the pylon inside. Below are the backward view of the model.
Graphics are from SolidWorks and Ansys Mechanical files.
Sorry for any inconvenience, I'm new to Ansys Workbench. Thank you.
