Right-click on a simulation set in the Simulation Sets branch and select either Include Project or Include All Projects.
If Include All Projects is chosen, all projects loaded under the Projects branch in the workspace will be added as tasks within that given simulation set. Alternatively, you may add individual projects from a drop list of loaded projects.
NOTE: A standard PSCAD license allows a maximum of eight simultaneous, parallel EMTDC simulations. For information on increasing this limit, contact the PSCAD Sales Desk (sales@pscad.com).
