Nozzle: Error
 
1 Attachment(s)
Dear Foamers,
I'm running 2D planar nozzle. Here is the files http://www.mediafire.com/?7a3j9j9jkmhc91l.

And I got this error message.

Could you give me some suggestion? I can't find which error!!! :(. If someone knows appropriate BC, guide me please!!!

Hi

the solver wants to solve the field "e" (not sure if rhoCentralFoam normally does this) and you haven't defined a linear solver for this field.

Best Regards,
Christian

It is not like that. I set the value for mu in thermophysical properties. Only "0" is accepted for rhoCentralFoam. I don't know the reason so far....
