Script for collecting CFD results from output files to dataframes and plotting them

While doing Computational Fluid Dynamics (CFD) analyses it is a typical problem to collect results from output files and compare them for the various geometries and load cases that were run. This script demonstrates how this post-processing work can be automated using Python. The output files with the CFD results are organized to a directory structure (v00, v01, etc.). The script can then:

• read the output files with the results
• collect them to pandas dataframes
• create plots with matplotlib:
• write the data to a spreadsheet (in excel xlsx format)

The example shows some typical data extracted from underhood flow simulations (heat exchanger data, part temperatures).
