Hello,
I want to model flow in a 3D tube, but i want to define a parabolic (Poiseuille) velocity profile at the inlet. Can somebody help me? The profile i want to apply is shown in figure (one of them). |

I have no idea what the blob in your image means.
Simply write a CEL function which describes your boundary velocity as a function of x, y and z and use it as the velocity component in a velocity inlet boundary. You do this either using analytic functions or 1D or 3D interpolation functions. |
