Webb9 sep. 2024 · One thing to add is that SMD is a solvation model (IEFPCM using SMD radii for electrostatic part, plus nonelectrostatic terms), so please do not combine SMD with other solvation models. The program should have recognized this error and abort, thank you for catching the bug. Webb19 maj 2010 · One of my final calculations was to be a QM:MM calculation (1 molecule:200 waters) with IEFPCM (solvent=water). The previous run (ONIOM without PCM) ran fine and converged after a reasonable time. However with PCM and after 168 processor hours, the calculation has not left the first MM stage. See below: INPUT: %chk=output.chk.
