Hi,
I would like to initialize my velocity field (U) with a function, for example a sine function depending on x-coordinate of the cell. Is there a way to do that? I am using OF-4.0.x version.

Thanks in advance.

Hi,
You can use funkySetFields from swak4foam to do that.

To add to that, here is a small example to initialise a spherical bubble in interFoam:

funkySetFields -latestTime -keepPatches -field alpha.water -expression "sqr(pos().x-0)+sqr(pos().y-0)+sqr(pos().z-.00150)<sqr(0.0005)?0:1"

Here a mask is used to set the field to 1 (~water) everywhere, except for a sphere with radius 0.0005 and center position (0,0,0.00150), where we set the value to 0 (~air).

Thanks for your advise. But I am unable to install swak4Foam for my current OpenFOAM 4.xx version. Any tips?

Why are you unable to do that?

I am using OpenFOAM 4.1 with swak4Foam just fine.

You should indeed use the development version if you wish to use OF41.

And I cannot help you any further without more detail.

Where exactly does it fail? What is the error?

I have installed swak4Foam correctly and solved my problem. Thanks.
