Hello Prem, nI would suggest you running a steady simulation first until the flowfield partially establishes in the domain and then shift to first order transient. I would also suggest you do a grid convergence study to make sure the mesh you have is fine enough to capture the physics. Another suggestion would be to start off with a slightly lower inlet pressure and then gradually increase it to the desired value. While checking for convergence, it is a good idea to monitor a variable(s) of interest along a location as this would give you a better indication of the convergence especially in transient flow simulations. n
