After fresh install of 2.2.0 I noticed there is no bubbleFoam solver.
See below the differences between the 2.1.1 and 2.2.0 installs.

Is it a problem on my end or with the distro?
Can someone confirm?

Thanks!

Greetings Chris,

I'm guessing you haven't read the release notes: http://www.openfoam.org/version2.2.0/index.php

This was part of a generalization they've made on all solvers: http://www.openfoam.org/version2.2.0/fvOptions.php

In theory, we can now take advantage of several features that previously only existed for some dedicated and hard-coded solvers.

Best regards,
Bruno

Thanks Bruno,

I had read through these, however I'm not sure I understand.
How does bubbleFoam get replace by more general cases?

Is the new method to use fvOptions with something like twoPhaseEulerFoam and include semiImplicitSource/codedSource for Drag/Lift/Virtual Mass source terms?

Thanks,

Chris

Hi Chris,

Sorry about that, I didn't look with enough attention into this... I simply looked at the question and it seemed all too similar to recent questions on the same topic: "where did X solver go?"

You seem to be already well ahead of me on this one... nonetheless, a quick search lead me to this very detailed page: http://openfoamwiki.net/index.php/BubbleFoam

My first instinct is to run the "./multiphase/twoPhaseEulerFoam/bubbleColumn" tutorials in both 2.1.x and 2.2.x, as well as comparing the results with "./multiphase/bubbleFoam/bubbleColumn" from 2.1.x.
If there was no conclusion from the results, then the next steps for me would be:

1. Ask about the "missing" solver and report the results in the bug tracker: http://www.openfoam.org/bugs/
2. If that doesn't work as expected, then from that wiki page I posted above, it seems that the main author of this page is Alberto Passalacqua: http://openfoamwiki.net/index.php/User:Alberto - his contacts are on that user page. He seems to be well informed on this topic!

And that's all I know

Good luck! Best regards,
Bruno

PS: I've taken the liberty to move this thread from the "OpenFOAM Installation" sub-forum to the main "OpenFOAM" forum, given that this isn't a specific installation problem

Just to close this thread.

bubbleFoam is dropped in favour of twoPhaseEulerFoam for OF 2.2.0.
