CFD Online Discussion Forums - Porous Media Setup in OF211

Hi,

I need to run a simulation with porous zones in OF211.

I've already ran the same simulation with OF230 but the setup of the porous zones - and the related files - is different from OF211, but I need to use that.

So, I created a "porousZones" file in "constant" folder, like suggested by the tutorial of the angleduct. And nothing else. I didn't create the fvOptions file which has been introduced from OF220 and neither the "PorosityProperties" file.

When I run the simulation in OF230, I get this:

Code:

Create time



Create mesh for time = 0



Reading field p



Reading field U



Reading/calculating face flux field phi



Selecting incompressible transport model Newtonian

Selecting turbulence model type laminar

Creating finite volume options from fvOptions



Selecting finite volume options model type explicitPorositySource

    Source: porosity1

    - applying source for all time

    - selecting cells using cellZone porous1

    - selected 1741 cell(s) with volume 8.97893e-07



Porosity region porosity1:

    selecting model: DarcyForchheimer

    creating porous zone: porous1

And it's all ok.

While, when I try to run the same thing in OF211 (with the modified files) I get that:

Code:

Create time



Create mesh for time = 0



Reading field p



Reading field U



Reading/calculating face flux field phi



Selecting incompressible transport model Newtonian

Selecting turbulence model type laminar

No field sources present

And no indication about the porosity.

Is it correct? Or am I doing anything wrong??

Thanks,
Regards
