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.
- Using Tutorial Macros and Files
  Macros, input files, and final simulation files for a range of tutorials are provided as an optional download package on the Support Center website. These macros and final simulation files are provided as an aid to the written tutorials, so that you can check your final results against the downloaded files, or against a simulation that is built and run using the macros.

  - Intermediate Java Macros: Run Multiple Simulations
    This tutorial simulates a train in a cross-wind, to calculate the drag coefficient on the train for different angles of attack.
    - Prerequisites
      The instructions in the Intermediate Java Macros tutorial assume that you are already familiar with certain techniques in Simcenter STAR-CCM+.
    - Importing the Surface Mesh and Naming the Simulation
      To set up the Simcenter STAR-CCM+ simulation, launch a simulation and import the supplied surface mesh.
    - Visualizing the Initial Surface
      Visualize the initial surface of the geometry.
    - Assigning Parts to Regions
      Before setting up the mesh for this tutorial, assign the imported part to a region.
    - Setting Up the Mesh
      To calculate the drag coefficient of the train as it is subjected to cross-winds at different angles accurately there must be enough cells near to the train, which requires a relatively fine mesh.
    - Specifying Boundary Types
      Specify the boundary types for the simulation.
    - Generating the Mesh
      The mesh parameters are fully defined and you can proceed to generate the mesh. It is good practice to generate the surface mesh and examine that before proceeding with the volume mesh.
    - Setting Up the Physics Continuum
      Physics models define the physical variables and phenomena in the simulation. In this tutorial, model the flow as Steady and Turbulent. Use the Segregated Flow solver with the K-Epsilon Turbulence model.
    - Setting Global Initial Conditions
      Set the initial flow field conditions. Retain the default value for the initial pressure condition, and specify custom values for turbulence.
    - Specifying Inflow and Outflow Conditions
      Set the boundary conditions on the inflow, outflow, rails, and railway bed boundaries. The inflow velocity is different for each cross-wind flow angle and so is set in the Java macro.
    - Creating a Drag Coefficient Report
      Create a drag coefficient report to obtain the value for the drag coefficient on the train at each cross-wind flow angle. Solution convergence can be monitored using this report also.
    - Creating a Velocity Magnitude Scalar Scene
      Create a scalar scene to visualize the velocity magnitude.
    - Creating a Scalar Scene with Streamlines
      Create a second scalar scene to display streamlines over the train.
    - Designing the Macro
      Carry out the following steps when designing a macro:
    - Recording the Initial Macro
      Before you record the initial macro, it is good practice to have a clear plan of which actions you perform when recording the macro. The resulting Java file is clearer and less cluttered, and identifying which statements refer to a particular action is much easier.
    - Creating the Final Macro
      You are ready to write the final macro.
    - Testing and Debugging
      Test and debug your macro.
    - Running the Macro
      Modify the macro to use your working directory to find the input file:
