Hi all,
I have a problem with convergence. Form the residual monitor,it seems like all the variables are keeping steady,however form the outlet surface monitor,it more likely the outlet velocity goes up and down and can not tend to be steady up till now(2000 interations) By the way,i extend exhaust with 1 meter long and choose outflow as BC. I do hope i can get some suggestions from you. Thanks! |

you have no need to monitor the outlet surface velocity, it's not accurate in general, however, if your problem is related with the output directly, you have to study which BC is the most suitable.
