Smooth iso-surface in Fluent

Captain Convergence · March 23, 2020, 08:34

Hi all, I am trying to generate a .gif with my transient simulation. I want to plot my Q-criterion iso-surface with a velocity coloring in Fluent itselft so I can export images during the simulation. I managed to do that but as you can observe in the attached image the contours are not very smooth, is there any way to generate the iso-surface from interpolated data rather than cell data? I couldn't see any option to smooth the iso-surface.

I am interested if you could suggest any other alternative.

Since the values on the nodes are interpolated from the cell values, there is a likelihood of degeneracy if node values are used for generation of iso-surfaces.
