Subtract temperature plots to find effect of changing parameter(s)

Hello,

Is there a way to find the difference between two temperature contours? I am thinking this would be a nice way to visualize the effect certain parameters have on the temperature field by visualizing ΔT.

I assume, to begin with I would need to be working with the same exact mesh file so that all the node values line up. However, I'm not sure if this type of post-processing is available.

Perhaps if I could export the node values I could create a plot in Matlab or similar software. Has anyone tried this before?

This can be done easily in CFD Post. Run your two cases, open both models in the same CFD post, and use the "Case Comparison" option.

Awesome! Thanks
