Tutorials
Tutorials show you how to use Simcenter STAR-CCM+ for various applications in a step-by-step format with recommendations for setup, initialization and steps of the solution process specific to the application. Macro and simulation files are available for download for a large proportion of cases.

    - Prerequisites
      The instructions in the Reacting Channels: Steam Methane Reforming tutorial assume that you are already familiar with certain techniques in Simcenter STAR-CCM+.
    - Loading the Starting File and Creating the Mesh
      A suitably refined parts-based mesh is provided for geometry parts that represent a firebox with internal reacting channels.
    - Defining the Firebox Physics
      Reacting physics models simulate combustion in the firebox. Co-simulation models exchange data between the firebox and the plug flow reactor code for reacting channels.
    - Setting up the Reacting Channels
      Reacting channel co-simulation is set up between the Plug Flow Reactor (PFR) in the reacting channels (where steam methane reforming reactions occur) and the firebox domain in Simcenter STAR-CCM+ (where combustion reactions occur).
    - Defining Physics Analysis Scenes and Plots
      Update scenes and plots to display physics values on geometry parts when running the reacting channel simulation.
    - Specifying Initial Conditions and Boundary Conditions
      Initially, before any combustion reactions occur in the firebox, the volume of the firebox contains air. These initial conditions are defined within the physics continuum.
    - Running the Simulation and Reviewing the Results
      You can review the progress of the simulation as it runs by monitoring the scalar scenes and reports that are set up.

Loading the Starting File and Creating the Mesh

A suitably refined parts-based mesh is provided for geometry parts that represent a firebox with internal reacting channels.

Before starting this tutorial:

Copy the following files and folders from the reactingFlow folder of the downloaded tutorial files to your working directory:
- RC_StartingSim.sim
- grimech30.dat
- SpeciesList.dat
- thermo30.dat
- transport.dat
- Either user-code-Linux or user-code-Windows
Make sure that you have at least 4 processes available to use.

Open Simcenter STAR-CCM+ and select Load Simulation.
In the Load Simulation dialog:
1. Set Process Options to Parallel on Local Host and Compute Processes to 4 or more—depending on availability.
2. Click Browse.
3. In the Open dialog, navigate to the reactingFlow folder of the downloaded tutorial files and select the file RC_StartingSim.sim.
4. Click Open, then OK.

Expand the Regions > Firebox > Boundaries node.

The following boundary types are specified.


Boundary	Property	Setting
FullFurnace.BurnerRight	Type	Mass Flow Inlet
FullFurnace.BurnerLeft	Type	Mass Flow Inlet
FullFurnace.Outlet	Type	Outlet
FullFurnace.Walls	Type	Symmetry Plane

All other boundaries are specified as Wall boundaries.

An automated mesh operation with various surface control mesh settings is set up and ready to mesh.

Right-click the Geometry > Operations > Automated Mesh node and select Execute.
When the mesh creation is complete, create a mesh scene.
The mesh is refined suitably for this tutorial analysis. However, to save computational expense, this mesh is coarser than the mesh which would be used for realistic industrial scenarios.
The simulation file also contains a pre-defined Temperature scene which you can use at a later stage to visualize the temperature on the reacting channel boundaries.
Save the file as Firebox.sim.
