Hi,

I'm trying to set different initial conditions for a set of cells. In the interFoam example, the boxToCell rule was used, hoewver, in my problem the boundary is not rectangular but rather circular.

What are the exact command lines that I should write in the setCellDict?
Should I specify each cell explicitly?

Thanks,

Rina

Hi Kathrin,
Thanks for your mail.
I have another question: if the blocks have a cyclic side, which command should I use? The code that you sent is for a sphere, which is not the case for me. The block has 3 straight lines and one is cyclic. How should I write the initial conditions?

Thanks again,

Rina

I am changing the interFoam tutorial to define a sphere of ratio 1 as initial condition. Does anybody know the error in this setFieldsDict file?






FoamFile
{
version 2.0;
format ascii;
class dictionary;
object setFieldsDict;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //


defaultFieldValues
(
volScalarFieldValue gamma 0
volVectorFieldValue U (0 0 0)
);


regions
(
sphereToCell
{
sphere (0 0 0) (0 0 1);


fieldValues
(
volScalarFieldValue gamma 1
);
}
);

Correct is that syntax:


sphereToCell
{
centre (0.02 0.135 0);
radius 0.01;
fieldValues
(
volScalarFieldValue gamma 1
);
}

Hello all,

does sphereToCell work the same way in 2D axisymmetric cases? The thing is that i want to patch a droplet with this syntax in setFieldsDict, but I get a cylinder instead of a droplet!! I tried funky function and cellSetDict but I got the same cylinder.

Any help is greatly appreciated, thank you.

I've never use it but funkySetFields should work.

See http://openfoamwiki.net/index.php/Co...funkySetFields example at point 5.

In 3D you can use the ellipsoid equation http://en.wikipedia.org/wiki/Ellipsoid

Regards,
