Collision Problem with Rotating Gears

Hello everybody,

i need your help. i am using Nvidia-Flex Particels as Collision but it doesn’t work correctly. The gears are touching and affecting each other without being in Contact (visually). i did add “Get World Delta Secounds” to apply the Delta Time like in the picture.

But it doese not solve my Colision Problem. now i am trying to finde another solution to make My Gear rotate and affect the second gear correctly in spite of the Nvidia-Felx Collision.

Cordially

Why not just rotate the second gear in the same manner? ( with BP ).

@ClockworkOcean thanks for your answer.and i understand your Point. But I am using UE4 for my research to test if we can use Gaming Engines in scientific Simulations. Thats why i need help to make the first Gear rotate using the rotation of the other Gear.
