hello
the residuals and monitored quantities keeps fluctuating in the steady state simulation so I tried to make under relaxation of 0.1 and time scale factor of 0.1( at iteration 7500 ) and it is still fluctuating too what else should i try to reach convergence of monitored quantities ? the problem : simulating water inside tank which is bing charged by heat pipes - k-w SST turbulence modelling |
