Hi,

Implementation depends on mathematical model. Right now it is not quite clear:

- Why convection terms are missing in temperature and mass transfer equations.
- Why mass transfer is outside of PIMPLE loop.
- You update kinematic density after solution of temperature equation, yet, since you have added mass transfer, kinematic density also depends on salt concentration.
- Do you have evaporation model? Is it just temperature dependent mass flux at the top of something more complicated?
- Since you would like to model lining layers, maybe you should consider modifying one of CHT family solvers, this allows you to have detailed description of heat transfer in the bottom area, also lining material is solid, you need only heat transfer there.

In 2.4.0 there is no noSlip boundary condition. You have to use "fixedValue" with "value uniform (0 0 0)". See U file in tutorials/heatTransfer/buoyantBoussinesqPimpleFoam/hotRoom/0 for example.

Also you need to fix changeDictionaryDict file, in 2.4.0 boundary dictionary has to be included in dictionaryReplacement dictionary.

To clarify, for anybody who isn't already aware, there are two different "branches" of openfoam: openfoam.org, and openfoam.com. This is documented, but you'll only find that documentation if you know to look for it. I didn't. I had to get tipped off when I asked a question. Not only is openfoam incompatible between releases of the same branch, it's (even more?) incompatible between branches. If you research the release histories of both, you will find that alexeym is using .org . At least for his example here. Other tutorials I've found that are helpful use .com . I've heard it said that the recommendation is for users generally to familiarize themselves with both, then.. well, then it seems to me that you've graduated to developer, since you might want to combine features implemented separately in both. Anyway, this is .org . Thank's for the tutorial aleseym!

I have tried to explain how everything is done in README.pdf.

One of the possible problems could be version incompatibilities: I use 5.x, you use 2.4.0, so you have to adapt certain BCs and maybe fvOptions configuration dictionary.

If you have question, post them here.

I have now tried to run the solar-pond. I get the following error in the log:

/usr/bin/buoyantBoussinesqPimpleFoam: symbol lookup error: /lib/libsolidSpecie.so: undefined symbol: _ZN4Foam8fileName20allowSpaceInFileNameE

..could this be a compatibility issue? or do I need to re-compile libraries..? (I've been looking at this: symbol lookup error).. I'm using openfoam-9..
