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.
  - 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.
    - Loading an Existing Simulation
      For this tutorial, you use an existing simulation file from the 3D-CAD: Cyclone Separator tutorial. This file contains the geometry for the cyclone.
    - Creating the Fluid Region
      To use 3D-CAD geometry in a simulation, you first convert the model to geometry parts, and then assign these parts to regions. After creating the regions, you define boundary types on flow boundaries.
    - Generating the Volume Mesh
      After assigning parts to regions, you can define the mesh settings for the simulation to generate a polyhedral volume mesh. For this simulation, the polyhedral mesher is used in conjunction with the advancing layer mesher to build a mesh suitable for predicting the swirling flow inside the cyclone.
    - Selecting Physics Models
      Physics models define the physical variables and phenomena in the simulation. In this tutorial, the K-Omega turbulence model is used to limit the simulation run time.
    - Setting Boundary Conditions
      For this simulation, a uniform inlet velocity profile with specified turbulence intensity is sufficient.
    - Preparing a Scalar Scene
      Use a scalar scene to visualize the velocity on a section through the cyclone chamber.
    - Running the Steady Simulation
      Before running the simulation, you define the stopping criteria. You are advised to run this tutorial on a multi-core machine with four cores.
    - Running Unsteady with Curvature Correction
      The accuracy of the simulation is improved by activating the curvature correction term of the k-omega turbulence model. However, this improved accuracy means that an unsteady solution must be adopted in order to achieve adequate convergence.
    - Creating a Streamlines Scene
      Create a scene to display the streamlines inside the cyclone separator.
  - 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.

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

    In industry, film casting is a common process for producing thin polymeric films. Cast films are used for applications such as food and textile packaging, stretch wraps, or plastic bags. 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.
