  - Airgap Remeshing: Electronic Speedometer
    Electric machine simulations require a conformal mesh at the interfaces between different components. Airgap remeshing is a meshing technique that allows you to generate and maintain conformal meshes between regions that are in relative motion.
    - Prerequisites
      To complete this tutorial, you require a double-precision version of Simcenter STAR-CCM+. Also, the instructions in this tutorial assume that you are already familiar with certain techniques in Simcenter STAR-CCM+.
    - Loading the Initial Simulation
      For this tutorial, you are provided with a starting simulation that includes the CAD model and regions that represent the magnet, the coils, and the main air domain.
    - Defining the Rotation Motion
      The magnet and the surrounding air rotate rigidly at 1 rps. Define the rotation motion and create a local coordinate system that follows the rotation.
    - Defining Mesh Operations for the Airgap
      In electric machine applications, it is common to generate a tetrahedral mesh for parts with a complex geometry and then extrude it to the parts that have a more regular geometry. For illustration purposes, this tutorial adopts the same meshing strategy, although this simple geometry could be meshed directly using the directed mesher.
    - Defining the Magnet Physics
      Select the physics models that define the magnet physics. To account for the rotation of the magnet, you define the magnetization direction in a local coordinate system that follows its motion.
    - Defining the Coils Physics
      Select the physics models for the excitation coils and define region settings.
    - Defining the Physics of the Air Regions
      As you are only interested in the magnetic potential solution, you model the air regions as a gas without selecting any flow model. Modeling air using a flow solver would require solving the equations of flow, which is not necessary in this case. For airgap remeshing, you require the Airgap Remeshing model.
    - Creating the Airgap Regions
      For the airgap, you require two regions—one region that rotates with the magnet and the surrounding air region, and a stationary region.
    - Generating the Mesh
      Generate the mesh and visualize it in a mesh scene.
    - Creating the Interfaces
      Setting up a simulation with airgap remeshing requires that you manually define interfaces. For airgap remeshing, you require a repeating interface between the airgap regions.
    - Creating Scenes and Reports
      For visualization, create reports for the magnetic flux linkage in the coils and the voltage induced in the coils by the magnet motion. Also create a vector scene that displays the magnetic flux density.
    - Running the Simulation
      Before you run the simulation, check that the interfaces are correctly defined and that the mesh is conformal.
    - Summary
      This tutorial demonstrated how to use the Airgap Remeshing model.

To create the reports:

Right-click the Reports node and select New > Electromagnetism > Magnetic Flux Linkage.
Select the Reports > Magnetic Flux Linkage 1 node and set Parts to Regions > Coils.
Right-click the Reports node and select New > Electromagnetism > Magnetic Motion Induced Voltage.
Select the Reports > Magnetic Motion Induced Voltage 1 node and set Parts to Coils.
Multi-select the Magnetic Flux Linkage 1 and Magnetic Motion Induced Voltage 1 report nodes, right-click and select Create Monitor and Plot from Report.
In the Create Plot from Reports... dialog, select Multiple Plots (one per report).

To visualize the magnetic flux density:

Create a vector scene.

Rename the Scenes > Vector Scene 1 node to Magnetic Flux Density and set the following properties:


Node	Property	Setting
Vector 1	Display Mode	Line Integral Convolution
Parts	Parts	select all regions
Vector Field	Function	Magnetic Flux Density

Save the simulation.
