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.
- Introduction
  Welcome to the Simcenter STAR-CCM+ introductory tutorial. In this tutorial, you explore the important concepts and workflow. Complete this tutorial before attempting any others.
- Foundation Tutorials
  The foundation tutorials showcase the major features of Simcenter STAR-CCM+ in a series of short tutorials.
- Geometry
  The tutorials in this set illustrate various Simcenter STAR-CCM+ features for creating and working with parts and 3D-CAD.
- Mesh
  The tutorials in this set illustrate various STAR-CCM+ features for building CFD meshes.
- Incompressible Flow
  The tutorials in this set illustrate various Simcenter STAR-CCM+ features for incompressible fluid flows as well as porosity and solution recording
  - 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.
  - 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.
    - Prerequisites
      The instructions in the Porous Resistance: Isotropic Media tutorial assume that you are already familiar with certain techniques in Simcenter STAR-CCM+.
    - Importing the Mesh and Naming the Simulation
      Import a polyhedral mesh from the incompressibleFlow folder, and save and name the new simulation.
    - Visualizing the Imported Mesh
      A geometry scene was automatically created after the import process. Examine the Geometry Scene 1 display in the Graphics window. Initially all parts of the mesh are shown as solid, colored surfaces.
    - Scaling the Mesh
      The original mesh was not built to scale and therefore requires scaling so that the dimensions of the porous region are 0.1 x 0.03 x 0.1 meters.
    - Setting Up the Models
      Models define the primary variables of the simulation, including pressure, temperature and velocity, and what mathematical formulation is used to generate the solution. In this example, the flow is turbulent and incompressible. Use the Segregated Flow model together with the standard K-Epsilon turbulence model.
    - Setting Boundary Conditions and Values
      The default boundary conditions on the wall and outlet boundaries are suitable for this analysis so the only user specifications required are on the inlet boundary. A fixed velocity of 20 m/s and appropriate turbulence parameters need to be specified there.
    - Specifying Porosity Coefficients
      As discussed in the introduction to this tutorial, the porous region is defined by its inertial and viscous resistance coefficients, which are 25 kg/m⁴ and 1500 kg/m³s, respectively. As the porous region is isotropic, these values hold in all directions. The coefficients, along with the turbulence parameters in the porous region, must now be specified.
    - Monitoring the Run Progress
      As part of the post-processing operations, make sure that the calculated pressure drop across the porous region is close to the theoretical drop given by [eqnlink.
    - Setting Stopping Criteria
      Rather than arranging for the analysis to run for a set number of iterations, it is often useful to specify stopping criteria based on residual values and monitored quantities. For this simulation, define a stopping criterion that checks whether the porous region pressure drop monitor has reached a steady value.
    - Visualizing the Solution
      View the velocity vector field as the solution develops on a plane bisecting the fluid and porous regions.
    - Running the Simulation
      Run the simulation and observe the Residuals plot, the monitor plots, and the vector scene.
    - Visualizing Results
      Examine the vector scene in detail.
    - Validating the Results
      As discussed at the start of the tutorial, the calculated pressure drop across the porous region can be compared to the theoretical pressure drop derived from the mass flow rate.
    - Summary
      This tutorial models flow through the 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.

    This tutorial demonstrates how to use the solution recording and playback module for capturing the results of transient phenomena.

Visualizing the Imported Mesh

A geometry scene was automatically created after the import process. Examine the Geometry Scene 1 display in the Graphics window. Initially all parts of the mesh are shown as solid, colored surfaces.

Click one of the parts.

The boundary selected is highlighted and a label with its name appears on the display.

In the Simulation window, the node that corresponds to this boundary is also highlighted.

Similarly, if any other boundary node is selected in the Simulation window, the surface corresponding to that boundary are highlighted in the Graphics window.

Left-click anywhere in the Graphics window and drag the mouse in any direction. The view rotates about the location where the left mouse button is clicked (marked by a small square).
Similarly, right-click and drag the mouse in any direction to pan or shift the display.
To zoom in and out, middle-click in the Graphics window and move the mouse up and down.
Rather than use the mouse facilities to adjust the view approximately, click the button at the top of the Geometry Scene 1 window and select Views > +X +Y +Z > Up +Z, as shown below.
Use the mouse buttons to zoom in and position the part so that it is similar to that shown below.
