Hello,nIt is okay to use a flow inlet boundary condition, as long as you are definitively aware of its value. To capture the jet flow properly, you will need a really good mesh. Please inspect the mesh from the AIC HW example. You will see regions of refinement to capture the jet spreading, inviscid core, and the mixing layer region properly.nThe floating-point error is referring to the fact that your model did not converge properly. What is your mesh quality? Also, what boundary conditions are you using in your problem? Please describe them properly so we can understand them better.nThank you.nKarthikn
