Hello, I am also trying to simulate the InterFoam tutorial, written by Hassan Hemida, I have used the boundary conditions given below but unable to reproduce the same result as given in the tutorial for the laminar case (doing laminar case first). May anyone kindly look at the initial boundary conditions and let me know whether it is fine or not.(I am trying to simulate water jet into air using interFoam.)

For U:
