Specifying the Coupled Region and Boundaries

To export data to gPROMS, you couple the fluid region with the gPROMS network, and couple the inlet, outlet, and wall boundaries with corresponding gPROMS environment zones and surfaces.

You specify the coupled regions and boundaries by defining coupling zones under the External Links > gPROMS File > Zones node. For each coupling zone, Simcenter STAR-CCM+ automatically determines the fields that are exported to gPROMS based on the specified coupled parts.

By default, Simcenter STAR-CCM+ creates three zones—a volume zone that represents the gPROMS network and two surface zones that represent the gPROMS environment zones. For this tutorial, you require four zones—one zone for the region and three zones for coupling the inlet, outlet, and wall boundaries.

  1. Expand the External Links > gPROMS File > Zones node.
To couple the Simcenter STAR-CCM+ fluid region with the gPROMS network:
  1. Select the gPROMS Network > Conditions > Part node and set Parts to SprayDryer.
    The External Volume Part is automatically set to the external region that represents the gPROMS network.
To couple the Simcenter STAR-CCM+ inlet boundary with the corresponding gPROMS environment zone:
  1. Edit the Inlet > Conditions node and set the following properties:
    Node Property Setting
    Surface Parts Parts SprayDryer > Inlet
    External Surface Part Parts gPROMS Network > Inlet (already selected)
To couple the Simcenter STAR-CCM+ outlet boundary with the corresponding gPROMS environment zone:
  1. Edit the Outlet > Conditions node and set the following properties:
    Node Property Setting
    Surface Parts Parts SprayDryer > Outlet
    External Surface Part Parts gPROMS Network > Outlet
To couple the Simcenter STAR-CCM+ wall boundaries:
  1. Right-click the Zones node and select New.
  2. Rename the Zones > Zone 1 node to Wall.
  3. Edit the Wall > Conditions node and set the following properties:
    Node Property Setting
    Surface Parts Parts SprayDryer > Bottom and Wall
    External Surface Part Parts gPROMS Network > Wall


  4. Save the simulation.
