Okay so the mesh quality is (maximum skewness is at 0.7898) , I think I should increase it further by decreasing the element size from 2.00 mm further downward in steps of 10% . I haven't added inflation , also the outlet pressure is at zero gauge pressure my literature states that there pressure drop was at 2000 Pa I get around 4000 Pa , also there are negative pressures recorded but after some runs it converges to zero as well . Shall I decrease element size and analyse further as I don't understand what's wrong in my pressure drop
