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.

  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.
  - 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.

Setting Up the Solution History File

Create a solution history, simh, file and use it to store selected solution data at specified time intervals.

Right-click the Solution Histories node and select New....
In the Save dialog, enter vortexSheddingData.simh as the name of the solution history file and click Save.

A new node containing the name of the solution history file is added to the object tree below the Solution Histories node.

The red asterisk next to this node means that data is actively written to the file when the simulation runs.

Another new node, vortexSheddingData, is added to the Solution Views node. The properties of the solution view node control the data shown by the representation associated with it.

Choose what data to save to the solution history file. As this is a vortex shedding case it is appropriate to store results for pressure, velocity and vorticity.

Set the following properties:


Node	Property	Value
vortexSheddingData	Functions	Pressure Velocity Vorticity
vortexSheddingData	Regions	Fluid_Domain
Update	Trigger	Time Step
Time-Step Frequency	Frequency	1

The Auto-record property records the data to the solution history file at the required intervals. If you do not want to record the data when the solver is running, deactivate this setting. The Path property displays the relative path to the simulation history file. The States property displays the number of saved states stored in the selected solution history file; currently this is displaying 0 as the solver has not yet run.

Save the simulation.
