Default no convergence due to simplified model
Posts: n/a

i'm modelling unsteady turbulent flow and was wondering if a lack of convergence is due to the use of a simplified model (solution controls), as my mesh i believe is adequate and at the beginning of the simultation, i.e. the first 5 time steps there is convergence. However after that there is none.
