Axisymmetric space problem
 

Hi guys...
I am creating a simulation for the modelling of swirl flows from a axial swirl burner.
For modelling the flow outside the burner(after coming out of the nozzle), I am facing a problem. I am using 2d simulation for the modelling off the outer regime.
I am exporting the velocity profile from the burner and importing it to the new domain.
What are the conditions necessary for exporting the profile??
Should the xyz coordinates at the exit of the burner and the xyz coordinates of the domain needed to be created be the same??
and what type of profile should i choose
Line profile or surface profile if im exporting to a 2d simulation?

Secondly i tried using a line profile and when i click axisymmetric it gives error
Invalid axisymmetric mesh with nodes lying below x axis.

Funny thing that the mesh quality i had used in planar 2d space was 1.00
Now when i changed to axisymmetric the quality is now coming as 0

Im totally confused. Please guide me
