Hello
I want to simulate in 2d an stationary bubble in a medium. I have found this paper, which it also has provided openFOAM components (actually not in a clean way). Using the damBreak and modifying a bit based on the provided code in the paper I have set up a case. But when I run interFoam it I get an error that "FOAM FATAL IO ERROR: keyword PIMPLE is undefined in dictionary", in another forum it is mentioned to change PISO in the code to PIMPLE and it will get solved, I did but it didn't. Also before running the interFoam when I open paraFoam to see the domain and initial conditions I get error that "inconsistent patch and patchField types for patch type empty and patchField type fixedValue". Could someone please help with this? or if someone know that someone here has already simulated a stationary bubble please let me know. I have seen the case on rising bubble but it is about some detailed issues, and as I am beginner to OF I would appreciate if someone can help. |

In your fvSolution file is a "}" missing, just before PIMPLE.
The case has many other problems too. I don't see any bubble in you mesh. I don't find any initial condition for the pressure in folder 0.

Thanks for your reply, I fixed my issues with the case, and now it's running, but the shape does not stay, or even come to the circular one, it starts circular but as it passes even comes into an square shape.
