Hi folks,

I'm not familiar with either 6 DOF or FSI and couldn't decide on which is best suited for my case, even after reading some posts.

I'm trying to set up a simulation where I have a structure inside a pipe that gets pushed towards another structure and starts rotating. I don't know the rotating speed (if I did I would use either MRF or AMI) only the inlet and outlet conditions of the pipe.

Anyone has some experience with this type of simulation that can provide some insight?

Also, it seems implausible based on what I've read, I'm assuming both these type of simulations are transient and no steady state is possible?

Thanks.

BR.
