    - Summary
      This tutorial has introduced the following Simcenter STAR-CCM+ features:
  - Abaqus Co-Simulation: Thermal Coupling
    This tutorial demonstrates how to run a thermal co-simulation case using Simcenter STAR-CCM+ and Abaqus. Co-simulation involves a strong coupling between the two codes, in which data exchange occurs at frequent intervals, that are known as coupling steps. In this case, data is exchanged at the end of each time-step, and a relatively large time-step is used to approximate a steady-state solution.
  - Abaqus Co-Simulation: Mechanical Coupling
    This tutorial demonstrates how to carry out a mechanical co-simulation case using Simcenter STAR-CCM+ and Abaqus. Co-simulation involves a strong coupling between the two codes. Data is exchanged at frequent intervals that are called coupling steps. This level of communication between the solvers allows you to obtain a full solution across the fluid-solid interface.
  - gPROMS File Export: Spray Dryer
    Simcenter STAR-CCM+ allows for one-way coupling with gPROMS, a process modeling platform for the simulation of complex systems. In Simcenter STAR-CCM+ you reduce three-dimensional solution data to discrete values defined for clusters of cells; data from these clusters can then be exported to a network in gPROMS.
  - GT-SUITE Co-Simulation: 1D Coupling
    This tutorial demonstrates the typical workflow for co-simulation with the engine simulation code GT-SUITE from Gamma Technologies.
  - Co-Simulation API: Spindle Valve
    This tutorial demonstrates how to use the Simcenter STAR-CCM+ Co-Simulation API (Application Programming Interface), in order to couple a partner program to a Simcenter STAR-CCM+ simulation. The partner simulation models the behavior of a spindle ball valve in response to a multiphase flow.

Mapping Boundary Data onto the Abaqus Surface

Record a macro to map Simcenter STAR-CCM+ boundary data to the Abaqus surface.

When the fluid solution has converged, the thermal data at the solid-fluid interface, that is, the Fluid-Wall boundary, can be mapped from Simcenter STAR-CCM+ to the INNER surface on the imported model. This data can then be exported in a format that can be used to define a thermal load in the Abaqus model.

Before carrying out the mapping and export processes, start recording the first macro. Once the recording has started, each action you perform in Simcenter STAR-CCM+ is included in the macro. Use this macro later on to repeat the map and export processes.

To start recording the first macro:

Click (Start Recording) to initiate the recording process.
In the Save dialog, enter loopMapExport for the name of the Java macro.
Click Save.

From this point onwards, any recordable action you make in Simcenter STAR-CCM+ generates lines of Java code in this page. Clicking

(Pause Recording) pauses generation of the Java code; clicking the same button resumes generation of the Java code. Clicking

(Stop Recording) ends all generation of the Java code and write the macro to file. Do not click either of these buttons for now.

Proceed by mapping the Simcenter STAR-CCM+ solution data onto the Abaqus model surface:

Right-click the Imported Models > Abaqus: exhaust node and select Map data > Surface Data...
The Map Imported Model Data dialog appears, which allows you to set up the mapping operation.

In the Map Imported Model Data dialog:

Set the following properties:


Group box	Property	Setting
Map Direction	Simcenter STAR-CCM+ to Imported Model	Activated
Mapping Inputs	Imported Surfaces	Imported Surfaces > INNER
	Boundaries	Regions > Fluid > Boundaries > Fluid-Wall
	Boundaries	Regions > Surface Extruder > Boundaries > Fluid.Fluid-Wall
	Data to map	Local Heat Transfer Coefficient (default)
Reference Temperature Evaluation Option	Use Local Heat Transfer Reference Temperature	Selected (default)

Click Apply then Close.

The Output window displays the time to map the data, and Done when the mapping process is complete.
