that sounds great. If you need some support with testing this with large models please let me know and I will run it on some of our models. Is there a rough idea about how and when this will make it into 1.5-dev/1.6-dev? Thanks. Regards Bastian |
Hrv, Martin,
I am just wondering how the ggi speedup work is proceeding? As far as I see there are now news about that in 1.6-ext so far? I started working around ggis to get my cases run in OpenFOAM which works but is a bad compomise in meshing. Regards Bastian Quote:

Hello Bastian,
This work is progressing slowly. On my side, the mixingPlane and some other non-OpenFOAM activities are sucking all my available time. Some improvements are coming though for speeding up the GGI. I have developed a replacement to the slow AABB neighbours search algorithm for the GGI facets. The new search algorithm is based on octrees, and is providing a 10x speedup. This will help when initializing the GGI interface, or when using the GGI with moving meshes. I have sent the code to Hrv so he can integrate this with 1.6-ext. As for speeding up the GGI in parallel, I know Hrv is working on this, and I will too as soon as I am done with the mixingPlane. The GGI is slow for my research group as well, so this is certainly a high priority for me. Best, Martin Quote:

Martin, Hrv, I see some changes made their way into 1.6-ext. I am currently compiling it. I see that the MixerGgi tutorial still uses globalFaceZones and therefore I think that this is still necessary? Which of the changes are already in and wich are still to come? Thanks. Bastian |

how slow is your algorithm at the moment. Lets say for 100K polygonals how much time you are taking?? (in seconds). Just wondering. |
Parallel performance of GGI went down in latest OF-1.6-ext?

Hi,
I've found the new update for GGI parallel performance improvement on the Git hub site. I was really looking forward to this, so I've download these update, and recompile the OpenFOAM-1.6-ext and tested my test case with GGI interface (see attatched image). But, in my test case (in parallel), computational time was much longer than the first release of OF-1.6-ext:confused:. I was really disappointed. Or, Did I made some mistake for setting new feature in GGI? |
