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.

  - Steady Flow: Lid-Driven Cavity Flow
    This tutorial demonstrates the performance of Simcenter STAR-CCM+ in solving a traditional square lid-driven cavity flow. The problem geometry consists of a two-dimensional 1 m² cavity. The cavity is covered by an impermeable wall that moves in the x-direction with constant velocity of 1 m/s. A stretched quadrilateral mesh with 6400 cells is used.
  - Steady Flow: Channel Flow with Multiple Meshes
    This tutorial describes a steady airflow simulation over an obstacle that is mounted at the bottom wall of a three-dimensional channel.
    - Hexahedral Mesh
      The first mesh for this tutorial is hexahedral. Create a new simulation and import the mesh.
      - Creating a Macro
        Record a macro file to avoid having to repeat the steps. Use this macro later to set up the cases for the other two meshes.
      - Setting Up the Physics Models
        Select the physics models for the gas.
      - Setting Initial Conditions
        Set some initial conditions for this simulation.
      - Setting Boundary Conditions and Values
        The default boundary conditions for the wall, outlet, and symmetry boundaries are all suitable so the only changes required are to the inlet boundary.
      - Setting Stopping Criteria
        The default stopping criterion is set to end the calculation after 1000 iterations. Such a value is excessive, so reduce the maximum number of iterations.
      - Visualizing the Solution
        Display velocity field vectors on the symmetry plane and contours of y+ values on the walls.
      - Setting Up Line Surfaces for Plotting
        Create two parts by intersecting a plane with the bottom wall and symmetry plane boundary surfaces.
      - Plotting Simulation Data
        Create plots of velocity and wall shear stress.
      - Initializing and Running the Simulation
        Initialize the solution and run the analysis.
      - Visualizing the Results
        View the vector and scalar scenes.
      - Examining Plots
        View the velocity and shear stress plots.
      - Exporting Simulation Data
        Export velocity plot data to a file for comparison with similar data produced using the other two meshes.
    - Tetrahedral Mesh
      This part of the tutorial models the same problem as the Hexahedral Mesh part, shown in the introductory Steady Flow: Channel Flow with Multiple Meshes section. However, the mesh used in this case is tetrahedral. All problem conditions and properties are defined using the java macro file created when setting up the Hexahedral Mesh case.
    - Polyhedral Mesh
      This part of the tutorial models the same problem as the previous two parts. However, the mesh used in this case is polyhedral. All problem conditions and properties are defined using the java macro file created when setting up the Hexahedral Mesh case.
    - Summary
      This tutorial described a steady airflow simulation, using three different meshing methods.
  - Steady Flow: Laminar and Turbulent Flow in an S-Bend
    This tutorial demonstrates the flow of an incompressible gas through an s-bend of constant diameter (2 cm), for both laminar and turbulent flow. The first part of the tutorial covers the laminar flow, with a Reynolds number (Re) of 500, and the second part covers the turbulent flow, Re = 50,000. The same pipe geometry is used in both cases.
  - Steady Flow: Backward Facing Step
    Steady flow over a backward facing step is a typical scenario to investigate the behaviour of reattaching flows. Understanding the behaviour of the flow is crucial for many applications such as designing heat exhangers, evalutating aerodynamic performance and improving flow control strategies.
  - Anisotropic Flow: Cyclone Separator
    The flow inside a cyclone separator is characterised by strong swirling motion and three-dimensional boundary layers. Properly accounting for these effects is a challenging problem for CFD simulations. This tutorial presents the initial step in setting up a coarse mesh cyclone flow simulation.
  - Porous Resistance: Isotropic Media
    This tutorial models flow through a catalyst geometry.
  - Porous Resistance: Orthotropic Media
    This tutorial solves the same problem as the Porous Resistance: Isotropic Media, except that the fluid in the porous region cannot flow in any direction other than the bulk flow (y-) direction.

Simcenter STAR-CCM+ provides a combination of the Film Casting model and the Free Surface model that allows you to simulate that process and to investigate the impact of various parameters on the resulting film.

Initializing and Running the Simulation

Initialize the solution and run the analysis.

Click the (Initialize Solution) button in the Solution toolbar or use the Solution > Initialize Solution menu item. The initial zero velocity condition is shown in the Velocity Plot at X = 0.38 display.
Click the (Run) button in the Solution toolbar to run the analysis.

The Residuals display is automatically created and shows the progress of the solver. The tabs at the top of the Graphics window make it possible to select any active display for viewing. Select the Velocity Plot at X = 0.38 display if you wish to observe the numerical solution development.

During the run, it is possible to stop the process by clicking the (Stop) button in the toolbar. If you do halt the simulation, it can be continued later by clicking the (Run) button. If left alone, the simulation continues until the stopping criteria are satisfied.
After the run is finished, save the simulation.
