Hi, I'm Hyunchang and just h
 
Hi,
I'm Hyunchang and just have started to use OpenFOAM.
We are to implement two-fluid model into 2phase flow, like spray, bubble...
For that, in starting step, I'm trying to solve channel flow where bubbles which have same diameter are passing.
So for that, I'm trying to change bubblecolumn case of tutorials.
I adjusted blockMeshdict and made new meshes and also change field data in 0 directory for the initial and boundary condition of our problem.
And then run the solver, twoPhaseEulerFoam by typing
"twoPhaseEulerFoam . channel_flow" in commander.
but I Have got error message like below.

It will be very kind of you to tell me any advice for this.

Many thanks.

Hyunchang.
