Reply To: How to input displacement to obtain deformation and motion in a body

Hi Adamya,

You can calculate the displacement of the face on which you have applied force by using directional deformation results in X, Y, Z direction and then in a new system, you can input those values as displacement boundary condition. See below:

 
Here, I quickly setup a simple cantilever beam model and applied a force of 10N in Z direction. I got -0.1592mm directional deformation in Z direction. Equivalent Von-Mises Stress is 26.61 MPa.
I took the -0.1592mm directional deformation, and applied that as displacement boundary condition to the face (For your model, you may have to consider all three X, Y & Z directional deformations).


After solution, you can see in the 2nd screenshot, the Equivalent Von-Mises Stress is almost same and force reaction is also 10N. 

Also, your model has multi-step analysis, so take directional deformation at all the time steps and apply displacement in same no of steps.
