Hello,
I've written previously with no success. My model uses the Laminar Flow module to solve the Navier-Stokes equation. One of the equations is a constraint, the continuity equation that states that div(u) = 0. However, when I plot the divergence of the velocity field, not all values are zero which implies that the velocity field must be corrected. In the dependent variables of the model there are the corrected velocity field components but apparently it is not possible to export those, so there is my first problem. But even if I'm not able to export the corrected velocities, is it possible to set a tolerance for the divergence value as a constratint to the equations?
Thank you!
