AsaheloMarinelo is on a distinguished road
I'm currently trying to simulate different kinds of objects (Washer, Plastic Cap, Nut, Bolt, etc) being pushed across a pipe system from Inlet to Outlet. So far I've been able to create simulations where I place the object (stationary) and observe the velocity and pressure contours.

How to generate dynamic simulation where the object moves alongside the fluid flow and reaches the outlet?. I want to also evaluate the mass flow rate differential that this object may be causing to the system. (Approximate how much restriction/obstruction is the object generating).

I've been advised to use deforming mesh (6DOF & collision detection), overset (also using 6DOF & collision detection) but I don't really know how to and have not found any tutorials online for beginners.

Thank you!
