Hi, i have a problem in 3D simulation,a symmetric aircraft cabin was simulated in 2D, it has 3 inlets projected downward at 3 passengers and 1 oulet at the side wall, as soon i make the model in 3D the model does not converge.

Thank you very much for your help

Well there could be lots of suggestions. Did you try to patch the solution paramters for the 3D from the 2D solutions.

For exmaple, for 2D, you have solved velocity components Vx, Vy. To start with 3D, patch the solutions of Vx and Vy and make Vz zero in all the whole domain.
