OpenFOAM vs FLUENT gradient schemes

FLUENT uses facelimited gradient limiters as their default but also sets leastSquares for the gradient schemes
https://www.afs.enea.it/project/nept...th/node369.htm However, most of OpenFOAM's tutorial uses Gauss linear gradient schemes without limiters It seems like leastSquares is more accurate than Gauss linear but if limiters are added to schemes it will decrease accuracy, thus may I know if "faceLimited leastSquares 1" or "Gauss linear" is more accurate? And whether "faceLimited leastSquares 1" or "cellLimited Gauss linear 1" is more accurate? |
