Hi all,

I have a question about the convergence in my model.
I am trying to simulate the water flow through a nozzle which is used in a surf simulator. I have tried different models, k-w sst and k-e, but in both situations the solution wont converge.

I have used velocity inlet, pressure outlet, steady state. Initialization from the Inlet (3.75 m/s). Two different meshes are used 340.000 and 510.000 elements, with a skewness average of 0.21 and max. 0.78. Orthogonal quality min. 0.26 and average 0.78.

I hope you can help me with this convergence problem, thanks for your time.

With kind regards,

Lance
