      I am attempting to run antenna array simulation using HFSS 2022 R1 on an HPC cluster with two nodes allocated via a Slurm scheduler. 

      Although the initial MPI test using mpirun.fl successfully executes the hf3d INTEL_MPI -mpi_mem_info command across both nodes and returns memory information from each, the actual simulation (including G3dMesher and hf3d iterations) appears to run only on the primary node, not utilizing both nodes as expected.

      I would appreciate your guidance on whether this behavior is expected and how to properly enable distributed parallelism across multiple nodes for this kind of HFSS job.
