I am unable to replicate the results in BaramFlow, despite using the same baseline mesh (loads without issue, thank you!), and the same turbulence model (Spalart-Allmaras). I believe the turbulence model is not being properly loaded by NextFOAM; this is probably a carryover from OpenFOAM's less than ideal implementation of this turbulence model (please see here: https://turbmodels.larc.nasa.gov/Papers/ChangesToOpenFOAM.pdf and here: https://www.cfd-online.com/Forums/openfoam-solving/238249-guide-switching-turbulence-model-spalartallmaras.html) for some more thoughts on that. I did attempt to manually modify the case file in accordance with gabrielfelix's excellent instructions, but despite this, the simulation results are quite inaccurate:
I think some changes to the BaramFlow GUI may be required to implement this turbulence model correctly, if it is a good choice. I think so, based on the NASA data...

Dev team,
I am working through solving a 2D flow case, specifically the NACA0012 airfoil baseline reference case provided by OpenFOAM here:
