Mamun New Member Join Date: Dec 2020 Posts: 23 Rep Power: 6	I am doing a simulation of the converging nozzle, under-expanded jet impinging on a water layer over a flat plate. At the inlet, I need to change the pressure gradually with flow time/iteration. How can I write an expression for it? Thanks
