    - Prerequisites
      The instructions in the Abaqus Thermal Coupling tutorial assume that you are already familiar with certain techniques in Simcenter STAR-CCM+.
    - Preparing the Abaqus Model
      In this section, you prepare the model for the exhaust manifold in Abaqus/CAE, including the corresponding Abaqus input file (*.inp).
      - Starting Abaqus/CAE and Importing Geometry
        In this tutorial, you are provided with a geometry of the exhaust manifold. Import the manifold geometry into Abaqus/CAE as a part.
      - Creating a Material
        Create a material definition for the manifold and specify the material properties that are required for a thermal analysis.
      - Defining and Assigning Section Properties
        Create a section from the material and assign it to the manifold part.
      - Creating a Partition
        As the manifold geometry is complex, a partition is created to aid in the meshing process.
      - Creating an Assembly
        An assembly contains all the geometry that forms the final finite element model. In this case, the assembly contains only the manifold geometry, which is added to the assembly by creating an instance of the part.
      - Defining Surfaces and Sets
        Specify the FSI interface as the inner wetted surface of the manifold model, and define two additional surfaces to specify thermal conditions on the manifold exterior and the flanges.
      - Defining the Analysis Steps
        Define the heat transfer analysis step.
      - Defining Initial Conditions
        Define the manifold initial temperature.
      - Defining Boundary Conditions
        In the heat transfer analysis step, the convection conditions and fixed temperature at the inlet become active. Specify the convection properties as interactions, since the manifold transfers heat to the surroundings. Specify the temperature condition at the inlet as a boundary condition.
      - Meshing the Model
        The next step involves defining and generating a mesh for the manifold part and is carried out within the Mesh module in Abaqus.

Preparing the Abaqus Model

In this section, you prepare the model for the exhaust manifold in Abaqus/CAE, including the corresponding Abaqus input file (*.inp).

It is recommended that you save the files for each application in separate subdirectories within an empty directory, to help you to organize the files that are created during the co-simulation.

In your working directory, create a directory /thermalCoSimTutorial.
In that directory, create two additional directories: /abaqus and /starccm+.

The files for the Abaqus part of the co-simulation are saved in /abaqus and the files for Simcenter STAR-CCM+ are saved in /starccm+.

If you are unfamiliar with Abaqus/CAE, it is recommended that you work through the examples in the Getting Started with Abaqus: Interactive Edition manual before attempting this part of the tutorial, in particular “Abaqus Basics”, section 2.

A copy of the input file that is created using Abaqus/CAE is provided in the Simcenter STAR-CCM+ installation. If you do not wish to work through the steps involving the preparation of the Abaqus input file, you can jump directly to the tutorial section, Preparing the Simcenter STAR-CCM+ Model.
