Aidan Guest Posts: n/a	the source term must be linearised with respect to the dependant variable. For example an x-momentum source term is linearised with respect to the x-velocity. I reccomend taking a look at the CFD wiki (http://www.cfd-online.com/Wiki/Sourc..._linearization) or "Numerical heat transfer and fluid flow" by Patankar (1980)
