Hi,
I tried to run FSI single wheel demo, It isn't delivering any Fz. I tried with changing the Ground material properties but not much progress. Is there anything am missing out.
Thank You

Hi Fahad,

When you said Fz, did you mean the force applied on the wheel from the granular material terrain? If the answer is yes, then Fz should be exactly equal to the weight of the wheel plus some extra weight of the rig parts. Since the wheel doesn't have any direct interaction with the rigid ground, you won't see any change if you only change the ground material properties.

Thank you,
Wei

That's the input data of the simulation, you can find it here. You can also print it on the screen. Just follow what we did for position, velocity, and such.

Thank you,
Wei

Hi,
But even the weight of the wheel is not delivered to the output file. Could you have a look please.

Hello Fahad,

When you say "not delivering any Fz", do you mean the "Fz" in the output file,  FSI_Single_Wheel_Test/fsi/FSI_body0.csv, not having values similar to the rig weight?

Thank you,
Luning
