hi all,
i am running a simulation with a mesh, which i created from two bodies independently. for the simulation i use cyclic acmi for the boundary at the transition surface. bc my case is rather large, i use multiple cores. however, i do not get the simulation to run faster with more than 30 cores bc i need to put the transition faces in one core. so my bottleneck is the cyclic acmi boundary that keeps all the faces in one core, and further usage of more cores does not lead to speed-up. does anybody have a tip or suggestion on how to improve the performance? thanks |
