Hello,



is it possible to have multiple
cellzones in one porosity definition ?

For example:
cellZone_1 and cellZone_2 should have the same porosity-1.




porosity-1
{
type DarcyForchheimer;

cellZone cellZone_1; cellZone_2;

d (0 0 0);
f (1e+5 1e+6 1e+6);

coordinateSystem
{
origin (0 0 0);
e1 (1 0 0);
e2 (0 1 0);
}
}

Off course, this notation does not work.

Best Regards

Hi Oliver,

AFAIK you cannot define several cellZones in one single porosity source.
But you can define as many sources as you wish, like this:

porosity-1
{
    type DarcyForchheimer;
    cellZone cellZone_1;

    d (0 0 0);
    f (1e+5 1e+6 1e+6);

    coordinateSystem
    {
        origin (0 0 0);
        e1 (1 0 0);
        e2 (0 1 0);
    }
}

porosity-2
{
    type DarcyForchheimer;
    cellZone cellZone_2;

    d (0 0 0);
    f (1e+5 1e+6 1e+6);

    coordinateSystem
    {
        origin (0 0 0);
        e1 (1 0 0);
        e2 (0 1 0);
    }
}

If the code duplication bothers you, this should work too:

porosity-1
{
    type DarcyForchheimer;
    cellZone cellZone_1;

    d (0 0 0);
    f (1e+5 1e+6 1e+6);

    coordinateSystem
    {
        origin (0 0 0);
        e1 (1 0 0);
        e2 (0 1 0);
    }
}

porosity-2
{
    $porosity-1
    cellZone cellZone_2;
}

I hope this helps.

This is indeed currently the best (the only) solution. It does add a bit more text input, but still ok for efficiency since the fvOptions loop over the cellIds of each cellZone anyhow.
