AEATECHNOLoGY ENGINEERING SOFTWAR About Convergence Convergence the solution has reached an unchanging state in CFx command file, the convergence criteria is set with the mass source tolerance the mass source tolerance is set as a percentage of total mass flow rate the solver defines convergence when the mass source residual is less than the mass source tolerance the mass source residual is not dimensionless it is the sum of the absolute values of the net mass flow rate into or out of ever ry cell. ve/ CFX-4 CFX4.3V4.3.1H Introductory Training(Dec 1999)CFX-4 Introductory Training (Dec 1999) 8 -5 CFX-4.3 V4.3.1H About Convergence Convergence: - the solution has reached an unchanging state. - in CFX command file, the convergence criteria is set with the mass source tolerance. - the mass source tolerance is set as a percentage of total mass flow rate. - the solver defines convergence when the mass source residual is less than the mass source tolerance. - the mass source residual is NOT dimensionless, it is the sum of the absolute values of the net mass flow rate into or out of every cell. |r| i i ncell =  1
