Hi,

Please refer Using Parallel Processing Capabilities (ansys.com) for use of parallel processing capability of System Coupling. RMB on 'Coupling participant' and click on 'parallel solve setup' specify the faction of cores to be used for each participant and total number of cores available. e.g with 12 cores available and fluent fraction of 1 and mechanical fraction of 0.5 will use 12 cores for fluent and 6 cores for mechanical.
