The Cleanup script is designed to do is Cleanup hung Fluent processes when running Fluent in Network Parallel. When running Fluent in Network Parallel if Fluent hangs on any one of the compute nodes you can double-click the Cleanup Script Batch file and it will end the process on all compute nodes. The Cleanup script on Windows is being written to where ever you start Fluent. If Fluent is exited out normally the Cleanup script batch file is automatically deleted except while using the GUI to exit Fluent. You can also safely delete any leftover Cleanup script files once Fluent has been closed out.
