    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.

    Thermal management simulations of headlamp applications allow you to identify temperature hotspots that can cause damage to the headlamp. Modifying the design—for example, including heat shields in the right places—leads to better and more durable designs.
    - Prerequisites
      The instructions in the Photon Monte Carlo Radiation: Headlamp tutorial assume that you are already familiar with certain techniques in Simcenter STAR-CCM+.
    - Loading the Starting File and Generating the Mesh
      For this tutorial, you use a simulation file that contains pre-prepared mesh and regions.
    - Creating the Physics Continua
      This tutorial requires two physics continua: one for the air and one for the solid components.
    - Setting the Initial Temperature
      To improve convergence, you set initial temperature values for the filament and the halogen bulb that represent a good guess of the final temperature field.
    - Assigning Materials to the Solid Components
      The regions for the opaque and transparent components contain multiple solid parts that you match with the defined materials.
    - Specifying Thermal and Radiative Boundary Conditions
      You set thermal and radiative conditions for the regions' boundaries. You specify the radiative conditions by assigning surface materials to the boundaries. At the walls of the opaque and transparent components, you set a convective condition.
    - Setting Up Scenes and Plots
      The starting file for this tutorial provides several pre-defined scenes and plots.
    - Setting Photon Monte Carlo Solver Parameters
      The Surface Photon Monte Carlo (SPMC) model uses a statistical solver to model photon transport.
    - Running the SPMC Simulation
      By default, the simulation stops after 1000 iterations. To judge convergence, you create two additional monitor-based stopping criteria.
    - Analyzing the SPMC Results
      After the simulation is complete, you visualize the results.
    - Refining the Mesh of the Transparent Solids and Housing
      In this part of the tutorial, you extend the simulation to include participating media radiation. As a first step, you refine the mesh of the lens, halogen bulb, and rear housing.
    - Modifying the Physics Continua to Model Volumetric Radiation Exchange
      You modify the physics continua to model volumetric radiation exchange in the transparent solid components and surface radiation exchange in the opaque components.
    - Reassigning the Transparent Components Region
      You associate the physics continuum that you created to model volumetric radiation exchange using the VPMC model with the transparent components region. This association resets the radiative boundary conditions to defaults and clears the materials that are assigned to the transparent solid parts. Therefore, you reassign the radiative boundary conditions and reassociate these parts with their materials.
    - Running the Simulation with Combined SPMC/VPMC
      Adding VPMC modeling to the simulation is computationally more expensive than running the simulation with SPMC modeling alone.
    - Analyzing the Effects of Volumetric Heat Exchange
      After the simulation is complete, you visualize the results. You compare these with the results from the first part of the tutorial, where you exclusively used Surface Photon Monte Carlo to model radiative heat transfer, to assess the effects that absorption has on the solution.
    - Appendix: Parameters
      The Surface Photon Monte Carlo Radiation: Headlamp tutorial uses multiple pre-defined parameters.

    Comfort is one of the main factors that consumers consider when deciding how they travel. Therefore, passenger comfort is one of the key criteria that influence the design process of enclosed spaces such as a car or aircraft cabin.
  - Parts-Based Shells: Exhaust Pipe
    Simcenter STAR-CCM+ provides support for thin-walled structures that are best represented by a single-cell layer during simulation. These single-cell layers are known as shells. One of the main advantages of using shell elements is that it reduces the computational time and resources required for simulations.
