define a convergence criteria in CFX-Pre
 
Hi,
How do I setup my simulation (CFX-pre) so that it will stop when "H-energy imbalance (%) in domain" is less than 1?

I am using CFX12.

Thanks,
Tony

Turn the imbalances convergence criteria on in the output tab and set the criteria to 0.01. Note that this will apply the imbalance criteria to all equations, not just the H-energy equation.

Thanks, But I didn't find 'the imbalances convergence criteria on in the output tab', is it in "solver control" or "output control"?

It is under Solver Control/Basis Settings/Convergence Criteria/Conservation Target in CFX-Pre.
