 April 30, 2007, 03:03 Getting Inlet Velocity Values through CCL or User #1 Shraman Guest   Posts: n/a Hi, I am trying to extract the value of local velocity at the inlet through CCL or User Fortran. Through CCL I can extract mass averaged velocity value but not the local velocity value. Can anybody help me in this? Regards, Shraman

The difficulty I am having is, I do not know the Total Velocity at the inlet. I know the Ptotal, Ttotal, Vtheta and angle between Vradial and Vaxial. So I have to express the velocity components (radial and axial) in terms of Vtotal and Vtheta and the angle between Vradisl and Vaxial. This is the reason, why I am looking for the total velocity or static pressure from the Solver. Please let me know if you have any solution for this. I can even call you up if I can have your contact number. my mail id is shraman.goswami@honeywell.com Regards, Shraman

You can access all of the solver variables through CEL. The short names of the velocity components in the x, y and z directions are 'u', 'v' and 'w' respectively, long names are 'Velocity u', 'Velocity v', etc. The total velocity is simply 'Velocity'. You can use CEL expressions in the place of values for any boundary condition, allowing you to easily customize your solution without FORTRAN. Finally, I highly recommend you contact your technical support rep for help on these topics and any necessary training. Regards, Robin
