Getting different vortex core in Fluent and CFD-post for the same Q value.

  Hello,
  I am trying to find an isosurface of a vortex core. The isosurface obtained in Fluent using Q-criterion (Q=1) is largely varying from the isosurface obtained in CFD post. What is the reason for that?

  Hello Raju,
  I believe the values might be normalized and thus non-dimensional in CFD-post. Can you confirm the units of your isosurfaces?
