Loading the Initial Simulation

For this tutorial, you are provided with a simulation file that contains predefined objects.

Load the initial simulation:
  1. Launch a double precision version of Simcenter STAR-CCM+.
  2. Select File > Load Simulation...
  3. In the Load Simulation dialog, click Browse...
  4. In the Open dialog, navigate to the electromagnetism folder of the downloaded tutorial files.
  5. Select AxialFluxMachineHO_start.sim then click Open.
    You are recommended to run this tutorial in parallel, using at least 4 cores.
  6. In the Load Simulation dialog, click OK.
  7. You can review the predefined settings by expanding the relevant nodes:
    Physics Continua
    The starting file contains three solid continua to define the physics of the coils, magnets, and stator teeth. Each use the Finite Element Magnetic Vector Potential and Ohmic Heating model, alongside other specific models:
    • Coils—Finite Element Excitation Coil and Excitation Coil Lumped Parameter models to calculate the electric current density produced by the coils and other quantities of interest.
    • Magnets—Permanent Magnet model to simulate the magnetization direction of the magnets.
    • Stator Teeth—Laminated Steel model to simulate the eddy currents in the laminated material.


    Regions and Interfaces
    The starting simulation includes solid regions for the magnets, double-rotor, coils, and stator teeth, as well as the interfaces between these regions. The interfaces are a mixture of in-place and periodic interfaces.

    Parameters and Field Functions
    The majority of the required parameters and field functions are provided in the starting simulation. Ia, Ib, and Ic field functions define the three phase harmonic current supplied to the coils as:
    I a = I o 2 sin ( ω t + 105 ° )
    I b = I o 2 sin ( ω t + 345 ° )
    I c = I o 2 sin ( ω t + 225 ° )
    where I 0 is the initial current, which is also provided as a parameter (I_0).


    omega parameter defines the magnitude of the angular frequency of the AC current, ω = 2 π f , where f is the frequency (100 Hz). Pole Pairs calculates the number of pole pairs from the number of poles (NPoles).
  8. Save the simulation as AxialFluxMachineHO.sim.
