Hi
I'm using viscoelasticFluidFoam for a shedding flow. If I use upwind for div(tau) I will have 25% error in amplitude of oscillations. ![]() If I use URF the problem of amplitude will be solved, but I will have a big error in Strouhal number (period time)! ![]() And If I use any other scheme for div(tau) the solution will be diverged (without URF)! ![]() The divergence is stated in a special point and diffuses in all of the doamin: ![]() this is the grid in this point: ![]() I don't know what I should do. |
