I have a rigid body that moves according to a set of governing ODEs, and I'd like to numerically visualize the vortices that are shed by this object. How could I proceed?
I've been reading up on the Navier-Stokes equation and have a better grasp of it now, and I've watched some tutorials on implementing a 2D solver. But, I still have some confusion:
Do I prescribe the movement of the rigid body, when trying to solve the N-S equations?
It would seem strange to do so, because the movement of the rigid body came from dynamical solutions to the governing ODEs.
