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.

    Simcenter STAR-CCM+ provides a suite of tools to help you prepare surface geometry so that it is ready for meshing. This tutorial provides an introduction to some of these tools, using the example of a brake assembly.
  - Parts-Based Meshing External Aerodynamics
    This tutorial demonstrates how to set up a simulation using the parts-based meshing approach.
  - Mesh Operations: Imported Control Valve
    This tutorial demonstrates how to use the surface and volume meshing operations within Simcenter STAR-CCM+ to generate a polyhedral volume mesh with prism layers for a single region. The inputs required to build a trimmed cell mesh with prism layers are also covered.
  - Meshing: Multi-Part Heat Exchanger
    This tutorial demonstrates how to use the surface and volume meshing tools while working with multiple parts within Simcenter STAR-CCM+.
    - Prerequisites
      The instructions in the Meshing Multi-Part Heat Exchanger tutorial assume that you are already familiar with certain techniques in Simcenter STAR-CCM+.
    - Importing the Surface Mesh
      To set up the Simcenter STAR-CCM+ simulation, launch a simulation and import the supplied surface mesh.
    - Defining the Part Surfaces
      Identify the flow, symmetry, and interface surfaces so that appropriate meshes for each can be generated.
    - Assigning Parts to Regions
      Before setting up the mesh for this tutorial, assign the imported parts to regions.
    - Defining the Region and Boundary Types
      Set appropriate types for the regions and their boundaries.
    - Selecting the Meshers
      Create a single Automated Mesh operation for both the fluid and the solid.
    - Setting the Mesh Default Controls
      Set the default controls to generate the mesh.
    - Disabling the Prism Layer Generation in the Solid
      Define a custom Surface Control to deactivate prism layer generation in the solid part.
    - Remeshing the Surface Mesh
      Since the surface remesher and volume mesher have been selected in tandem, you could proceed and generate both meshes in one go. However, for training purposes, first generate the surface remesher mesh and view it before proceeding with the volume meshing.
    - Generating the Volume Mesh
      Run the polyhedral and prism layer volume meshers.
    - Summary
      This tutorial demonstrated how to use the surface and volume meshing tools while working with multiple parts within Simcenter STAR-CCM+.
  - Directed Meshing: Electrical Machine
    This tutorial demonstrates how to use the directed meshing tool in STAR-CCM+. Directed meshing allows you to generate a high-quality structured mesh by creating quadrilateral elements on a surface of a body and then sweeping them through its volume.
  - Local Wrapper: European Truck
    Local wrapping speeds up re-execution of the surface wrapper after local changes are made to the input geometry or wrapper settings.
  - Gap Closure in Surface Wrapper: Drone Main Body
    When using the surface wrapper for geometries that have feature-level holes or gaps, you can find that the core wrapper is unable to cover the whole surface with a closed wrap. To assist, Simcenter STAR-CCM+ provides a gap closure option that detects and fills these larger voids in the surface.
  - Turbomachinery Mesher: Compressor Stage
    When modelling the flow in turbomachinery applications, a flow-aligned structured mesh is required for accurate solution analysis. The Turbomachinery Mesh operation in Simcenter STAR-CCM+ generates a flow-aligned structured mesh from user-specified input surfaces and parameters.

Generating the Volume Mesh

Run the polyhedral and prism layer volume meshers.

To run the polyhedral and prism layer meshers, either:
- In the Mesh Generation toolbar, click (Generate Volume Mesh), or
- Select Mesh > Generate Volume Mesh.
As before, the output from the meshers is shown in the Output window and status updated in the status bar. When the process is complete, the message Volume Meshing Pipeline Completed is shown in the Output window. A summary of the mesh generation process for the core and prism meshes can be viewed by scrolling up the Output window.

To view the volume mesh representation:

Right-click the Scenes > Geometry Scene 1 node and select Apply Representation to Displayers > Volume Mesh
The scene updates to show the polyhedral volume mesh with a prismatic near wall layer for the fluid region:

A close up of the mesh in the vicinity of the inlet plenum is shown below:

To view the properties of the fluid volume mesh, including the number of cells in the fluid region:

Expand the Representations > Volume Mesh > Finite Volume Regions node and select the Fluid Body node.

Similarly, to view the properties of the solid body volume mesh:

Select the Solid Body node.

The exact values for cells, interior faces, and vertices differ to the above depending on the machine precision.
