Could someone please suggest a way forward for fluent to account for buoyancy forces? I tried what Kremella suggested still i am getting the drag force on the object equal to its weight which suggests that buoyancy forces are negligible. But with glycerine as fluid medium, we should see substantial buoyancy forces theoretically. Can someone put a light on this? Apart from my fluent settings in the above pictures, the below picture shows what i am simulating.
