Hi.......

While trying to iterate my turbulent jet model in an axi-symmetric problem, I'm getting an error message like,

iter continuity x-velocity y-velocity k epsilon time/iter
Error: > (greater-than) : invalid argument [2]: wrong type [not a number]
Error object : nan

can anyone help in sorting out the problem.
Any help is much appreciated in advance.

Thanks and regards...

This error pops up when there are intialization problems. For instance you "might" have checked on 2D but you have a axsymmetric problem. If you use UDF allocate correct number of memory terms. Check and hopefully it gets resolved.

Hi krisp........

Thanks for your reply, but my model still is not working. I'm not using the UDF and all settings I'm doing based on the fluent tutorial. But still I'm getting "Not a number".
Is there any other suggestions.......

TIA........
