LJ202505013133 4 months ago

Which post processing tool is recommended for comparing LES (made using CharLES), RANS and wind tunnel oil flow visualization results to each other?

First, what data type do you need to compare the contour or line plots?
Second, for RANS simulation, which software are you using?

If you are using multiple simulation software, you can export the result file and utilize the Tecplot software.

Please go through the following link before making any comparisons.

Overview of DNS, LES, and RANS Turbulence Models

The discretization methods of LES and RANS differ. In LES, the governing equations are discretized using filters, which resolve large-scale turbulent eddies and model the smaller ones. However, in RANS, discretization is based on resolving the mean flow and modeling turbulent fluctuations.

Many thanks.

Can Tecplot work well for > 1 billion cell mesh LES simulations?
