scotch decompose for dsmc
Hi All,
i'm doing some simulations with the dsmcFoam solver and read this paper: http://eucass2011.conferencecenter.r...papers/382.pdf There's a discription of a "new" scotch decompose-method witch deals with the number of particles per CPU.(Section 5) This looks quite promising, due to the particle-based calculations. :) Does anyone knows if its implemented in OF2.3.0 ? I couldn't figure out... :confused: (If, how to use it, strategy-keyword or something like this?) Tüdelü qwert |
Hi,
thanks for pointing on that dsmc paper http://www.openfoam.org/download/source.php depending on your Linux distribution installing Scotch can be sudo apt-get install libscotch-dev http://www.openfoam.org/docs/user/ru...s-parallel.php http://www.openfoam.org/mantisbt/view.php?id=1048 |
Hi Elvis,
thanks for your reply. Maybe there's a misunderstanding: I know the 'regular' scotch decomposition. In the paper i've pointed in my last post, there is a discription of an extention of these method: At their cases they could reduce time consumption by ~30% in contrast to the cell-based scotch method. :) Is this extension (mentioned in the paper) includet in version 2.3.0? I didn't found out (searched in ~/../OpenFoam-2.3.0/scr Or I misunderstood and there's a hidden hint somewhere in your links and I didn't get it :cool: (blind). Did anyone tried out this method. As I mentioned, it seems to be very promising for larger problems. best regards, qwert |
