Hi Foamers,
can i do a spatial domail decomposition which does not only cut my mesh into slices/blocks but also subdivides these blocks further? In other words (or actually its pictures :-), what know how to do is this: Code:
|--------+--------+--------| | | | | | 1 | 2 | 3 | | | | | |--------+--------+--------| | | | | | 4 | 5 | 6 | | | | | |--------+--------+--------| | | | | | 7 | 8 | 9 | | | | | |--------+--------+--------| Code:
|--------------------------| | | | 1 | | | |------+---+---+---+-------| | | 5 | 6 | 7 | | | +---+---+---+ | | 3 | 8 | 9 | 10| 4 | | +---+---+---+ | | | 11| 12| 13| | |------+---+---+---+-------| | | | 2 | | | |--------------------------| Is this possible with OpenFOAM and if so, how do I do it? Thanks and best regards Thomas |

Hi Thomas,
it is possible, just look for "manual decomposition" in decomposeParDict and in the forum. The drawback is that you would have to write your own tool to provide the processor number for each cell. Best, Pablo |

Hi Pablo,
thanks a lot! Manual decomposition seems to work fine. As there is no tutorial in the current OF version, future readers may find this thread helpful: http://www.cfd-online.com/Forums/ope...computing.html Best, Thomas |
