Automate OpenFOAM Post processing Using PyVista | CFD Data for Machine Learning

Manual post-processing in ParaView can be a bottleneck when generating large CFD datasets. In this tutorial, I show how to use PyVista to fully automate OpenFOAM post-processing and build datasets that can be directly used for machine learning. Topics covered: Loading OpenFOAM results in PyVista Automating visualization and data extraction Exporting CFD fields for ML pipelines Creating scalable datasets for data-driven modeling This approach is ideal for anyone working on CFD-driven ML, digital twins, or high-throughput simulations.
