WebAug 21, 2024 · The ''MGRID'' subsection defines how the integration grid used in QUICKSTEP calculations should be setup. QUICKSTEP uses a multi-grid method for representing Gaussian functions numerically on the grid. Narrow and sharp Gaussians are mapped onto a finer grid than wider and smoother Gaussians. In this case, we are telling … Webintegration grids reveals large uncertainties in computed free energies for some isomerizations, torsional barriers, and regio- and stereoselective reactions. The result is that predictions based on DFT-computed free energies for systems with very low- frequency vibrational modes can change qualitatively depending on molecular ...
