convergence problem in CFX

ibadullah safdar · April 21, 2016, 11:40

Dear all,
I am astonished

of CFX behavior that I attained convergence by taking mass flow rate value of air as 0.1 kg/s and water as 0.01 kg/s. But when I increased the mass flow rate of water to 0.03 kg/s then convergence did not take place up to 750 iteration and the RMS residual becomes stable with small ripples in graph. So can anyone tell me why the convergence is not taking place at increased mass flow rate. Please help me out
