  - Parts-Based Meshing External Aerodynamics
    This tutorial demonstrates how to set up a simulation using the parts-based meshing approach.
    - Prerequisites
      The instructions in the Parts-Based Meshing External Aerodynamics tutorial assume that you are already familiar with certain techniques in Simcenter STAR-CCM+.
    - Overview
      There are several stages within the Parts-Based Meshing External Aerodynamics tutorial.
    - Importing the Surface Mesh
      Launch a simulation and import the supplied surface mesh.
    - Storing the View
      Set up and store a convenient view of the geometry for use throughout the tutorial.
    - Preparing the Initial Surface
      In this stage of the tutorial, you remove the original wing from the car and import a new wing that is in a different position. These steps create several problems on the geometry surface, which you fix at later stages of the tutorial.
    - Filling a Hole on the Car Surface
      Use the fill hole mesh operation to fill the hole in the surface mesh that appeared when you removed the initial wing.
    - Creating a Composite Assembly
      One of the advantages of parts-based meshing is that you can perform mesh operations on an assembly of several parts. Here, you create an assembly to contain the parts that you are using in this tutorial.
    - Generating a Wrapped Surface Mesh
      At this stage you generate a surface wrap of the Vehicle Assembly to fix the pierced faces. You also set up curve controls and contact prevention to maintain important features on the surface mesh.
      - Creating and Setting Up the Surface Wrapper
        Create a surface wrapper operation and set the properties that apply to all geometry parts on which it operates.
      - Refining the Mesh on Part Curves
        To make sure that you capture the detailed features in the surface mesh, apply mesh refinement to all the part curves.
      - Preventing Contact between Close Surfaces
        To make sure that these two surfaces do not touch each other in the wrapped surface, apply a contact prevention between the nose and main body.
      - Executing the Surface Wrapper Operation
        Execute the operation to generate a wrapped surface.
    - Creating the Fluid Volume
      The fluid simulation requires a volume mesh between the surface of the car and the walls of the bounding box. To create the part that defines the outer surface of the volume mesh, you subtract the output of the surface wrapper operation from the bounding box.
    - Assigning the Fluid Volume to a Region
      Before generating a volume mesh, you must assign the fluid volume to a region. This action allows the mesher to convert the volume mesh to a finite volume representation that the solvers can use.
    - Setting Boundary Types
      Certain boundary types affect the volume mesh. In this tutorial, you have a velocity inlet, pressure outlet, and symmetry boundaries that do not require prism layers. Simcenter STAR-CCM+ does not grow prism layers on these boundaries by default .
    - Generating the Volume Mesh
      Use an automated mesh operation to generate the volume mesh.
    - Replacing the Wing and Executing the Pipeline
      An advantage of parts-based meshing is that when you have defined the series of mesh operations, you can repeat them on different initial geometries.
    - Summary
      This tutorial demonstrated how to set up a simulation using Parts-Based Meshing.
  - 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.

    This tutorial demonstrates 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.
