 January 27, 2011, 19:07 Plotting Radial Velocity and Tangential Velocity in CFD Post #1 Senior Member   Ashkan Javadzadegan Join Date: Sep 2010 Posts: 255 Rep Power: 16 Hi all I applied cylindrical velocity components at inlet of a pipe as inlet boundary condition as below: Axial Component: 0.175*(1-(r/R)^2) Radial Component: 0 Theta Component: 0.02*r I want to plot Radial Velocity and Tangential Velocity along the pipe but I do not know how? I just can plot the Cartesian component of velocity (u,v,w) in CFD Post. Does anyone know how I can plot Radial Velocity and Tangential Velocity in CFD Post? Best regards, AshtonJ

In CFD post when I wanted to plot axial, radial and circumferential velocity components, I got this error: "No data exists for variable "Velocity Axial" specified in object series 1.” However, I went to Turbo mode, defined my rotation axis and clicked calculate velocity components. Does anybody know how to fix this problem? Thanks Regards, AshtonJ
