Creating a solver for porous media
 

Hi all,

I am relatively new to openFoam. I have run a small number of simulations with openfoam before, with only minor changes to the fvSchemes and fvSolution files.

I am faced with the task of creating a solver to simulate flow in porous media; and I have decided upon the governing equations and boundary conditions.

It would be great if someone pointed me in the right direction to start - I would like to learn on:

1. How to discretize the governing equations,
2. How to code on OpenFoam,
3. The effects of the mathematical models in openfoam

Thanks a lot in advance!

There are various solvers, methods to model flow through porous media (see e.g. https://github.com/OpenFOAM/OpenFOAM...rousSimpleFoam) -- a search through the forum/google should provide ample information.

You will find a full tutorial to program a solver for porous media over there (from page 86) including basics of openfoam programming.

Hey all,


Thanks a lot.


I will look at these links and learn.

Hey Cyprien,



I had went through your presentation on OpenFOAM programming.



I am facing a little bit difficulty in understanding the 'semi-discretization' of the NS equations for the icoFoam solver.



My project requires a steady state simulation, so I understand that I would need to use a SIMPLE loop to solve for pressure. Would I need to do 'semi-discretization' there too? Where can I read about this?


Thank you so much and sorry for the trouble.



Cheers!
