    An important analysis for automotive applications is to simulate the thermal behavior of components during cold-start conditions. As the timescales involved in fluctuating fluid behavior often varies significantly from the timescales in solid thermal behavior, it is not efficient to run an implicitly coupled conjugate heat transfer simulation. Simcenter STAR-CCM+ provides a coupling strategy that permits distinct transient timescales for the solid and fluid components.

    - Prerequisites
      The instructions in the Surface-to-Surface Radiation tutorial assume that you are already familiar with certain techniques in Simcenter STAR-CCM+.
    - Importing the Mesh and Naming the Simulation
      To set up the Simcenter STAR-CCM+ simulation, launch a simulation and import the supplied volume mesh.
    - Splitting the Boundary
      One of the solid boundaries must be split into non-contiguous boundaries.
    - Renaming Regions and Boundaries
      The simulation currently has the default region and boundary names. Choose more meaningful names.
    - Creating Interfaces
      Simcenter STAR-CCM+ requires the existence of interfaces between different regions to transfer the appropriate physical quantities during the calculation.
    - Setting Up the Models
      Models define the primary variables of the simulation, including pressure, temperature, velocity, and what mathematical formulation is used to generate the solution. In this example, the flow is laminar and incompressible.
    - Setting Material Properties
      You change the default material for the solid continuum to glass.
    - Specifying Surface Materials and Radiation Properties
      You specify the radiation properties—emissivity, reflectivity, and transmissivity—at the boundaries and interfaces in this simulation. You do this by creating and defining a surface material for each boundary and interface.
    - Setting Boundary Conditions and Values
      The thermal insulator consists of a closed heated box with two internal solid glass panels that are surrounded by air. The boundary specifications that are required for this analysis are wall thermal conditions and radiation properties at the boundaries.
    - Setting Solver Parameters and Stopping Criteria
      Adjust solver controls such as the under-relaxation factors and the maximum number of iterations.
    - Visualizing the Solution
      View the temperature of the fluid and solid regions as the solution develops.

      In this case, a report and plot are used for monitoring the irradiation at one of the interfaces between the glass panels and surrounding air.
    - Initializing and Running the Simulation
      To verify that the initial conditions for the regions are correct before you run the simulation, Simcenter STAR-CCM+ allows you simply to perform solver initialization and then view the results using an appropriate scene.
    - Visualizing the Results
      To examine irradiation, temperature, and other results from the converged solution, look at the plots and the scene.

Splitting the Boundary

One of the solid boundaries must be split into non-contiguous boundaries.

Use the following steps:

Expand the Regions > Default_Solid > Boundaries node.
Right-click the Default_Boundary_Region node and select Split Non-Contiguous from the pop-up menu.
The boundary is split into four and three new boundary nodes are created as shown.
Save the simulation.
