VOF (interfoam) vs moving mesh (icoDymfoam)
Hi all,
I am pretty new to OpenFOAM and I was wondering if you guys have some advice on the usage of either of the two methods specified in the title for a surface tension dominated two-phase flow problem. Thanks in advance! |
Hi,
I use interFoam for capillary driven flows and I don't think that you can use icoDymFoam for a multiphase flow as it is just solving for single phase flow with a dynamic mesh. So surface tension effects are, as far as I know, not modeled in icoDymFoam but in interFoam. Please correct me, if you know better. Best regards, Lars |
well, I am not sure. But if the dynamic mesh solver can do free-surface boundaries then it can be used for gas-liquid systems by neglecting the density and viscosity of the gas.
Does it have a free-surface bc? |
Hi Michiel
Maybe you should consider the following article to be inspired from: http://powerlab.fsb.hr/ped/kturbo/Op...tionFAMENA.pdf Have a nice weekend Niels |
Hi Niels,
Yes that is exactly what I am looking for! Thanks! Do you know whether that solver is already available in OpenFOAM 1.7.1 ? A good weekend to you too Michiel |
Hi Michiel
It has been a while since I read the article, so I do not know (1) what is the name of the solver they are using and (2) whether or not it is available in 1.7.x. If you could make a summary regarding (1) someone (or I) might be able to help you further. Based on the authors, I would guess that the solver might be available through the OpenFoam-extend in version 1.5-dev. Best regards, Niels |
Michiel, I think that paper describes interTrackFoam, which can be found in the community version of OpenFoam (OpenFoam extend develop).
|
Great! Thanks guys, thanks anton!

Have you considered using interDyMFoam? It is a VOF, dynamic mesh solver already present in at least 1.7 if not in earlier versions.

Hi Dave,
I think interDyMFoam is a very good choice if I opt for the VOF method. I do think however that I will prefer Langrangian interface tracking (like interTrackFoam has) because I am very much interested in the precise surface curvature But thanks for the suggestion! |
