Simulation results do not change, despite change in value applied to the forces.

I am quite new to simulation software, so it might be misuse of my part, but whenever I perform a  FEA simulation in altair inspire personal edition, I get the same results (as in visual deformation of the part) independently of the load that is applied to it. I would like to know if this is a limitation of the software, or something that I did not properly configure. I will leave a video attachment showing how I perform the simulations.

    Hi Kaua,

    The results do change if we examine the maximum displacement.

    With the 100 N load the maximum displacement result shows 2.149e-01 mm.

    With the 0.1 N load the maximum displacement result shows 2.149e-04 mm.

    ps. the background music was a nice touch!

     

    Hope this helps!

    Thanks for the reply, it helped a lot! I am glad that you liked the background music.

    Is it possible to "exaggerate" the displacement shown on the 3d model? That would make visualizing how it behaves under different loads quite a bit easier. It also seems that the deformation of the object in shown in 3d, is not "to scale" to the real deformation, is there a setting for it to display the results to scale?

    Hi Kaua,

    The displacement in the video is already quite exaggerated. 

    In the animation settings (3 lines beside the play buttons at the bottom of the screen) you can change it from AUTO to any scale factor you'd like.
