    - 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.
  - CGNS File Import: Stress Analysis with Imported Fluid Loads

Modifying the Abaqus Input File and Running the Abaqus Job

Use the solution data from the fluid solution to define a thermal load in the Abaqus model.

Add a command in the Abaqus input file:

Open the exhaust.inp file in a script editor of your choice.
Scroll down to the section that begins with the following:
```
**
** STEP: Step-1
**
```
This section of the file, up to *End Step, contains the history data for the Abaqus job, including solver parameters, boundary conditions, loads, and outputs.
To cause Abaqus to read in the heat transfer coefficients from the mappedHTC.inp file, add the following lines that are shown in bold text:
```
*Output, field, variable=PRESELECT
*Output, history, frequency=0
*Include, input=mappedHTC.inp
*End Step
```
Save the file under the name exhaust-mod.inp and exit the script editor.
In a shell/command prompt, run the Abaqus job using the modified input file by typing the following command:
```
> abaqus interactive job=exhaust-mod
```
where abaqus is the command you use to launch Abaqus.
The set of files created after running this job are named exhaust-mod.*
