Dear OpenFoam user's,

I am trying to setup a case in OpenFoam 1.6 for simulated a slug air - water two-phase flow in a micropipe but instead of a using all geometry; I trying to use an axi-symmetric approach. I build my mesh using a blockMesh in according to the UserGuidde.pdf from OpenFOAM using the wedge boundary for the front and back plane, still I am usage the setFields function to set a stratified flow to start the simulation.

Really, I don't know what's happend because my simulation stop suddenly after read p, U and alpha1 in the first step.

This is the message in the konsole:

Exception for flutuate point

Please, help me. I don't know where is the error or if is possible using interFoam with axi-symmetric mesh??? Also I post my case if anybody could be evaluate !!!

I would check your boundary conditions and mesh, see this line:

time step continuity errors : sum local = 1.816956462e+279, global = 1.816956462e+279, cumulative = 1.816956462e+279

Dear Eelco Gehring,

Sorry but don't attend you, i retunr for a congress on multiphase flow. Do you revised my case and found any error in the implementation.

I look a forward to hearing from you!!
My deep regards

Sorry Javier, but you're going to have to look at the case by yourself for now. It is around that time where I am finishing up my thesis, so please check it out yourself and see if you can figure it out.

Hi, Javier,

I revised your blockMesh. I did not check your BCs. I did not get the initial error you encountered.

after untar the case, run ./runCase. It will do blockMesh, setFields, and then, run interFoam.
