Join Date: Feb 2010 Location: University of Stuttgart Posts: 66 Rep Power: 16	Hello everybody, I have find out, that the parallel performance of AMI is not good or even bad for simulations above ~100 cores. Description of my (test) case: -40M elements -4 different meshes coupled by GGI/AMI -one of them is rotating (turbine) -transientSimpleDyMFoam -partitions: 128, 256, 512, 1024 -versions: 1.6-ext and 2.1.1 Has anybody similar results or suggestions on improving something? Best regards, Timo
