convergence issues (discontinuity mastered!)
ok, so i have the continuity problems fixed (thanks for all the help). However, now i have convergence issues(i think). I've done about 30,000 iterations and its not converging...residuals are just oscillating: continuity 1.2-1.3e-3, fvar 1.3-1.4e-3, p1 1e-4-1.5e-5.
I'm modelling a tangentially fired coal boiler, following almost exactly the Fluent tute on non-premixed combustion(only geometry different). Running in steady state mode, k-epsilon, p1 radiation..etc...the same as the tute.
Should i be running this in unsteady mode? Also, should i expect a better convergence than this?
