In serial use the -on option to specify the name of the remote machine and your user name on that machine.
% starccm+ -on myusername@myremotemachine ~/airfoil.sim
The workspace will be started on the machine from which you issued the command but any server started from the workspace will be started on the remote machine.
You can also specify the path where STAR-CCM+ is installed:
-use-path-env
The installation of STAR-CCM+ to which your $PATH environment variable points will be used. This permits you to have the same installation in different directories on different machines as long as the PATH properly points to the correct location on the different machines.
