Are you using same file to run locally and on cluster? if yes, and seeing different results, try comparing solver output files. 

if you are running the same project on the cluster, and seeing different results, this could be due to ill constrained problem or numerical instability and/or Operational randomness and numerical round-off inherent to parallelism as explained in:

2.2. Troubleshooting (ansys.com)

and 

4.6. Troubleshooting (ansys.com)

Note that differences in results due to Operational randomness and numerical round-off inherent to parallelism should be minimal, so the initial things to check would be:

1. if it is the same problem or not? this includes mesh, geometry, and also unit systems.
2. if it ill-conditioned or not?
