Dear FOAMers,

I am pleased to inform you the release of a toolbox for OpenFOAM dedicated to the multiphase flow in porous media.

The source code is available at :
https://github.com/phorgue/porousMultiphaseFoam.git

Details about the method, validation, numerical tests can be found in the related publication "An open-source toolbox for multiphase flow in porous media" published in Computer Physics Communications :
http://www.sciencedirect.com/science...10465514003403
Please cite this paper in you use this toolbox in your future work.

Feel free to propose improvements, code corrections or any other possible development. Objective is to use this basis to implement later new physical features.

So maybe now we can post a bug report about this "porousInterFoam"....

We discussed a lot about that point but I'm not sure that "porousInterFoam" can be considered as bugged. From my point of view, porousInterFoam can be used in some specific cases, even if I'm not able to precisely define this conditions (First the capillary effects must be negligible, which reduces dramatically its field of application, but it is not sufficient).

But you are rigth, we should at least put a "warning" on that solver to explicitly explain limitations to users who start porous media simulations.

Nice tool, Pierre!

Another condition in which porousInterFoam solver cannot be applied is when gradients of porosity exist. There was a bug report posted more than 2 years ago, still to be responded...

Yes, I agree. The bug report relates to the fact that the cells fill up completely with water, even though there is essential just room in the pores; essentially leading to a too slow flow through a porous structure.

Therefore, I agree that porousInterFoam should not be considered for anything. For cases where capillary effects are negligible, e.g. coastal structures, both IHFoam and waves2Foam seems to perform nicely (and the programming is similar); but the constraints of those implementations should clearly be kept in mind. I will have a look at your paper now, as it appears to be an important addition to the modelling of porosity.

Kind regards,

Niels

Greetings to all!

I noticed that there is also a presentation for this toolbox available on the workshop at Zagreb of this year, namely "OFW09.0031 A porous multiphase flow toolbox for OpenFOAM": http://openfoam-extend.sourceforge.n.../download.html

Best regards,
Bruno

Dear FOAMers,

The porous media toolbox is now available also for foam-extend 3.1. A dedicated branch "extend-version" has been created with minor changes in the github repository and you can download it with:

git clone -b extend-version https://github.com/phorgue/porousMultiphaseFoam.git

Regards,

Pierre

Greetings to all!

@Pierre: I've created a basic wiki page to help getting your toolbox known to the community that uses OpenFOAM technology: http://openfoamwiki.net/index.php/Co...MultiphaseFoam

May you or anyone else feel free to update that wiki page!

Best regards,
Bruno

[Pedro24]

Hi,

Thank you for the basic wiki page, I'll try to find some time to update it

I have also created a dedicated branch of foam-extend nextRelease to implement the porous media toolbox directly inside foam-extend 3.1. I asked for merging this branch in order to make solvers and the porousMedia library natively available for the next release. Let's see if the extend community is interested.

Regards,

Pierre

Hey,

I had problems compiling the toolbox, the make commands could not find some of the .H files.
Fixed it by adding " -I$(LIB_SRC)/meshTools/lnInclude \" to the /make option files.

Julian

Greetings Julian and welcome to the forum!

Can you please let us know which OpenFOAM version are you using?

Best regards,
Bruno

[jdrgmr]

I'm using OpenFoam 2.4.0. Just started using OpenFOAM last week.

Regards,

Julian

[Pedro24]

Hi,

Thank you a lot for your bug fix Julian.

I updated the github version to be compatible with OpenFOAM 2.4.0 (and corrected a bug of field name from the last update, making tutorials not working).

Regards,

Pierre

Dear FOAMers,

The porousMultiphaseFoam toolbox has been extended to the groundwater flows with a new solver : groundwaterFoam and updated libraries.

The toolbox is still available at : https://github.com/phorgue/porousMultiphaseFoam.git

and the technical report on the new solver (model and validation) : https://hal.archives-ouvertes.fr/hal-01206922v1

Regards,

Pierre

Hi dear friends
How I can add porousMultiphaseFoam toolbox to my openFoam?
My linux distribution is ubuntu 15.04.
openFoam version: 2.4.0

Quick answer: I've added detailed installation instructions here: https://openfoamwiki.net/index.php/C...MultiphaseFoam

[jamalf64]

Thanks in advance

[jamalf64]

Hi dear friends
Unfortunately I got error during installation.
Please help me to fix that.

Best Regards
Jamal

Hi Jamal,

You need to activate the OpenFOAM environment. It depends on how exactly you installed OpenFOAM. Detailed instructions on this topic are available here: http://openfoamwiki.net/index.php/In...with_the_Shell

Best regards,

Now, there are 2 porosity zones with different parameters in my case, how can I define porosityProperties/constant ?
