Hello Basharat,
First, I would check that the version of Scheduler is supported along with the MPI version installed:
Scheduler Support:
https://www.ansys.com/content/dam/it-solutions/platform-support/job-schedulers-queuing-systems-support-2022-r1.pdf
MPI Support:
https://www.ansys.com/content/dam/it-solutions/platform-support/message-passing-interface-support-for-parallel-computing-2022-r1.pdf
Then, check Chapter 3 in the "Running Fluent using a Load Manager" Help documentation.
