Error: Floating point error: overflow
 
Hi everyone
I have a question
i am simulation two phase flow at fluent
air=primary phase----------water liquid=secondary phase
air velocity=10m/s &water velocity=1m/s
i am use the schiller naumann for drag
and slip velocity i am use manninen - et-al
but when i am run simulation This message is appear
((Error: Floating point error: overflow))
can some one help me ?

Are you sure about the phases are not other way around, ie Water being primary and air being secondary?

hi
i am sure
air carried water droplet toward filter
air= primary phase=i am sure

There can be several reasons for the floating point error. If your case is transient than try reducing the time step. A relatively bigger time-step can be the reason behind this error.

I hope you have fine mesh else that could also be another problem.
