Hello there,

I'd like to extract the flow field at the outlet of a radial turbine rotor to be used as inlet condition for a diffuser with a circular inlet section (the diffuser has a squared outlet section so unfortunately I can't use periodic conditions). I've ran steady-state analysis for the turbine. In CFD Post I can generate the full annulus solution at the outlet (please see the figure attached). However when I go to export and select the variable I need, the file that is generated clearly contains only the solution in the single passage. Is there any way to extract the flow properties from the full annulus outlet section? Thanks for any help

In CFX-Pre you should be able to expand that single profile to cover the full 360. It is under tools->expand profile data. It is probably covered in the help under that name as well.
