Simulation incorrect lego

[Anonymous]

I made a LEGO block and applied 200N (~20Kg) to the top of the block. However it totally deformed. When i stand on a LEGO block irl nothing happens and ofcourse I weigh more than 20KG.

But isn't the simulation working incorrect here? I checked everything again and my design was right also the material (ABS) was right. The simulation still shows me that the block just deforms. 

When I stand on a lego nothing happens to it so the simulation is just incorrect. If not could you run the simulation of 200N force and see if it works? I'm really new so it could just be me not using the simulation tool right.

Are you judging the deformation because it "looks like a lot" or are you going by the actual deformation value?

Fusion Simulation exaggerates the deformation display by default so you can actually see where deformation occurs.  In most cases, actual deformation is so small that you wouldn't be able to see it.  You can adjust the scale of the deformation display with the Deformation panel in the Results toolbar. 

You should also check the Safety Factor, that's going to be a better indication of whether the block will deform permanently or break.

Yes I was indeed judging it by the way it looked. Thanks for letting me know the simulation exaggerates the deformation! 🙂
