In case you need to mount a remote folder so you can work with it like a local folder:
sshfs navpex:/home/navabi/ai_sim_model/ ./navpex_folder/
This command uses the navpex ssh alias from the ssh config to mount the remote folder ai_sim_model as the local folder 'navpex_folder'. Under the hood SFTP is used to realize the access, but of course a the current user needs public-key access to the host iself.
To unmount the folder:
fusermount -u navpex_folder
