Hi all,
i am trying to simulate a baffle that is closed the first 60 sec. then it opens for the fluid for 60 sec and so on. There for I wanted to use a sin - function like that: sin (xxxx) > 0 -> baffle open sin (xxxx) < 0 -> baffle closed In that case it should be possible to use groovyBC is that correct? Further more is it possible to solve that problem with an steady-state solver? And finally - what patchtype should it be? wall patch cyclic In my opinion it could be a patch type Thanks in advance tobi |

You can accomplish the same thing with attachDetach mesh modifier. This requires to have a new topoChangerFvMesh; you can probably use the one I submitted for this bug report:
http://www.openfoam.org/mantisbt/view.php?id=572 Make sure you make the change mentioned in the third to last note about creating a new pointfield and then moving the points. This is working in both 1.6-ext and 2.2.x. |
