Place the attached file runfluentwinhpccorespernode.cmd on the Windows Desktop Right click runfluentwinhpccorespernode.cmd and choose edit Modify the following lines, to specify where you want the calculation to run on your system, the number of compute nodes to use and the number of cores to use per compute node rem Set the name of the Windows HPC scheduler head node set zheadnodename=%computername% rem Network share location where the ANSYS software is installed set zansdir=\%zheadnodename%ANSYS Incv%zver% rem Network share location where the calculation will run set zrundir=\%zheadnodename%ansysworkdiransysdev rem Set the number of compute nodes to use set numnodes=2 rem Set the number of cores to use per compute node set ncorusepnode=2 Save the file Right click runfluentwinhpccorespernode.cmd and choose open The command file should run. Read in the standard StaticMixer example into Fluent. Then run the calculation under the Microsoft HPC Job Scheduler, using the specified number of nodes and cores per node
