Solving a 3D turbulent problem
I am trying to solve a 3D turbulent flow (K-epsilon) over the front of a passenger car,with velocity, wall,pressure outfield, and symmetry boundary conditions as the input velocity reaches 10 m/s the solution starts to oscillate. I am using (K-epsilon) with second order upwind discretization with relaxation parameters mom as 0.5 turbulence parameters 0.4 each.
thanks in advance
