Floating point error
 

I have been trying to iterate my system for a while but everytime i hit on iterate, the problem floating point error and reversed flow always occur. I have changed from one method to others. none of them worked out. BTW, my system is a venturi which two inlet and one outlet. i am dealing with two phase system which one inlet is for water and another one is for air flow. Have u all had the same problem with me? COuld u share with me how to tackle it?

Thank you

Re: Floating point error
 

Lots of factors need to be considered. Are you feeding the right velocities? Did you check your grid? Can you list all models you are using?

Re: Floating point error
 

My model : 3-D, segregated, 2-Phase flow, Mixture, steady, k-e model. I was trying to decrease the relaxation factor but apparently it didn't work out that way. Do you have any suggestion or advise for my system? It always shows either

Error: Floating point error: invalid number

Error Object: ()

or reversed flow.

What are the superficial velocities of both phases?

Re: Floating point error
 

I put the superficial velocity data for the initial data. THe air inlet superficial velocity is about 3.2724 m/s and the liquid superficial velocity is about 0.482 m/s. SInce i have the system under gravity, i put gravity acceleration -9.81 m/s2 in define menu. Another thing i encounter right now is when i am running the fluent, something says"turbulent viscosity limited to viscosity ratio of 1.0000e5" COuld you tell me what that means? Thank you in advance. I really appreciate of your help
