Hi,
CFX does not use SIMPLE, and there is no CEL options to turn it on. CFX is a fully coupled solver between momentum and pressure equations and SIMPLE is uncoupled - they are fundamentally different. Glenn Horrocks |

Hi,
It depends on what you are simulating, but in general a fully coupled solver is faster and more robust to converge but uses more memory. There has been extensive discussion about this area previously. Do a search of previous postings for more information. Glenn Horrocks |
