Flow past sphere

Please login with a confirmed email address before reporting spam

Hi all, I am trying to model Stokes flow past a sphere and calculate the drag force on the sphere. I get the right type of streamlines in COMSOL however I am facing challenges in getting the drag force to converge to the analytical solution within 10% accuracy. I am currently trying to make the domain bigger and bigger to simulate an infinite space. I have heard that there are ways to implement infinite boundary elements in COMSOL. Does the fluid mechanics module support that feature? If yes, can someone please share an example in a 3D geometry? Regards Archit
