Hello all, I have a question.

I am simulating a jet flow. waht I found an interesting phenomena, If I use simple method for pressure-velocity, I got one direction of the flow. then I switch to the coupled method, I got the flow attached to the opposite wall.

I am wondering is the method cause the difference?

what about if I just use the same method, but run different times? will I get the same result for all the running or will I get different results?

anybody has a clue?

thanks
