      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?
