Hi Dr. Roberto,
Inorder to submit jobs to a HPC cluster environment from a Windows or Linux client in the same network, please ensure to install and run RSM Launcher service for the same ANSYS version on the headnode of the HPC cluster.
The RSM launcher usually runs on the port 9212 for ANSYS version 2021 R2
Please ensure the Firewall on the HPC side allows communication from and to the client on that port.
