  Hello all,
  I try to simulate a falling in Fluent. A square object in 2-D with 1.25 kg falls with gravity -9.81 m/s2. Phase 2 is water but it falls until hits the ground. No bouyancy force is acted. domain is all on +x and +y. No coordinates are negative. You may see on screenshot, it bends water but no touch after 1 sec. What should i do?

  Hi,
  You can try 6DOF solver to calculate motion of the moving body and you can use vof multiphase model to model the buoyancy force experienced by the moving body.
