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. Oguzhan |

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