hello,
I need to simulate flowing compressible or incompressible fluid in a circular pipe, containing two solid bodies moving by the drag force deduced by the fluid. The diameter of the bodies is the same magnitude of the pipe diameter and of course something like particles simulation won't fit.
Any suggestions? please

thanks
roi

Isn't the behaviour of such bodys chaotic? Can COMSOL simulate it?

Hi, no, it's behavior is not chaotic, simple steady state can be achieved. Basically it's just a particle in a flow filed, but rather in macroscopic concept in microscopic concept.
