Recorded OpenPFC stills
These four images are presentation treatments of recorded OpenPFC output. They are not browser sketches, and they are not a new simulation. tools/render_simulations.py rebuilds them from the scratch fields named below. Python 3.11, NumPy, and Pillow are enough.
manifest.json is the machine-readable record from the last run, including measured ranges and byte sizes. The OpenPFC master named there was used to audit the website. It is not the revision that produced every field.
Colors on the three flat fields run from ink through copper to cream. That scale is chosen for the site. It is not a solver colormap. The Taylor-Green figure keeps the isosurface colors of its ParaView render.
Copyright in the OpenPFC outputs is held by VTT Technical Research Centre of Finland Ltd, under AGPL-3.0-or-later.

tungsten_hip - OpenPFC revision: not written in
provenance.txt. None is inferred. - Treatment: presentation colormap and enlargement. The pixels are the mesh samples, not an interpolated image.
