I am trying to run the damBreak4phase case in RAS turbulence model, however, the RAS model is uninterpreted, and the kEpsilonCoeffs are not able to be read.
I also try to use multiphaseInterFoam to calculate my case with three phases, and the same problem is met.
The terminal prompts are attached.
Have a nice day!

Floating exception

[henry]

You are getting a "Floating exception" so it looks like you have not initialized the turbulence fields appropriately.

Hi, Dear Dr. Weller, thanks a lot for your friendly and precious comments. I am trying to improve the initialized turbulence fields. And I also try to use the laminar model to calculate my case, and when Time = 0.056, the similar error is met. Another comments?
yours sincerely,
Chiven

Hello, Dear Dr. Weller, now the liminar model is OK for the damBreak4phase case and my case. For the RASModel, I try to initialize the turbulence fields again, like the U, k, and epsilon, but fail and the same error is met. The BC setting is show in follows. The k and epsilon are obtained from
k=1.5*(5%*Ux)^2
epsilon=(Cmut^2*k^1.5)/(0.07*Dc), Dc is diameter
The k and epsilon setting way is OK for the single-phase turbulence calculation.
I also have tried to use boxtocell to set the fields of U, k,and epsilon.
Now, I have no idea about this problem. Especially I am amazing why the kEpsilonCoeffs{Cmu 0.09; C1 1.44; C2 1.92; sigmaEps 1.3;} can NOT be read.
Thank you very much!
Best regards,
Chiven

Hey Guys,

did you figured out how to run multiphaseInterFoam with RASModel?
I get almost the same message!

Thanks in advance

sarah

[mali]

Hi All,

I got the same problem. Any updated solution to this turbulent initial condition for multiphase dambreak problems?

[mali]

Hi All,

After many attempts, I found that by setting the boundaryfiled of the /nut to zeroGradient, the simulation run without any error.

Cheers

[sarahk]

Hey mali,

nice, thanks a lot!
Do you use zeroGradient just for the walls, or for in- and Outlet as well?

Greetings

sarah

[Elham]

Hi,

Would you please someone explain to me what the following part of multiphaseInterFoam mean?

    forAllIter(PtrDictionary<phase>, phases_, iter)
    {
        phase& alpha = iter();
        ...

Cheers,

Elham
