Dear, I am trying to run a
I am trying to run a simple case of a liquid bubble moving in another liquid.
I use OpenFoam 1.4.1
The DICPCG solver needs about 20 to 300 iterations, right from the start and this does not diminish. I use a very small time step (1e-7).
For the solver settings, I used the standard settings of the DamBreak case.
My model is simply a pipe system (3D) through which the main fluid flows, including a small pipe inside the larger pipe where the bubbles are injected.
Is it normal that the solver needs so many iterations per time step?

First make sure that your courant number does not exceed 0.2. Next how bad/good is your mesh? Finally, if everything is going fine except for simulation time, then try using the GAMG solver as opposed to the DICPCG solver.
