Hi,

I am calculating a flow field with backward velocity at the inlet and outlet boundaries. Please tell me how to set the inlet and outlet boundary conditions for this flow. Thank you very much !

With best regards, You

(1). As a general rule, you should set your inlet and outlet conditions such that it will simulate the test conditions.(as if you are running the test in the laboratory) (2). Because of the nature of the iterative algorithm used, it is possible to have reverse flow during the iteration process. There is not much you can do there,because it is part of the method used in the code. (3). But if you provide a better initial flow field, then it should improve the situation.
