Conveniently, every RSM installation has a single-node ARC already configured. This is the localhost configuration in the HPC Resources list:

The localhost configuration automatically makes each user's local machine a single-node cluster. It provides immediate job submission capability for all users, enabling them to submit certain types of jobs to their local machines using the Local queue that is defined in this configuration.

In the default localhost configuration, the Name and Submit host are both set to localhost, and cannot be changed. The HPC type is set to ARC, indicating that the Ansys RSM Cluster (ARC) scheduling system will be used to submit jobs to the cluster. Since jobs are only being submitted to the local machine and not a remote one, only the Able to directly submit and monitor HPC jobs option is available.

When the Submit host is the local machine ('localhost'), only two file transfer options are available on the File Management tab, because the HPC staging directory is on the local machine:
