Hi everyone:

My model is a pipe flow with one inlet and two outlets, which diameter is variable with the flow direction, and there is a symmertrical plane at Z=0 and XY-plane. The caculation had be finished in Fluent 6.1.

Now I want to use Tecplot software to draw some velocity profiles (X-axis is the diametry, Y-axis is the velocity magnitude) within the symmertrical plane along the flow direction.

I had tried many ways but no success. How can I do it? Please give me any suggestion, or if there is a tutorial ralated to the problem?

You try to interpolate the field value in the fluid zone to the symmertrical surface firstly, then plot the velocity magitude.
