Hi, I'm a new learner of FLUENT. When I was to set the converge criteria, I find that the criteria of fluent is a sum of residuals at all the cells if it is unscaled. And if it is scaled, the criteria becomes the maxium of the first 5 sum redisuals divide the sum of the redisuals of the current interate. Anyway, I can't get a direct criteria that when all the redisuals meet it, the interate stops. Is there a way to define the criteria like this?

I dont understand your question? Are you asking what are appropriate convergence criteria?

Yes. For example, I want the residual of continuity to be smaller than 1e-5 at each cell. How can I set the criteria? Both scale and unscale or normalization do not meet my request.
