Running the Simulation

Prepare analysis objects, set up the solvers and run the simulation.

  1. Set up scalar scenes, reports, and plots to visualize the solution and monitor the quantities that are relevant to your analysis.
    See:
    By default, the solution is available at cell centroids for all models. Even though the Finite Element Magnetic Vector Potential model computes the magnetic vector potential at element edges (see H-Curl Hierarchical Shape Functions), Simcenter STAR-CCM+ internally interpolates the solution at cell centroids.
  2. Specify stopping criteria as required.
  3. Expand the Solvers node and set up the solver properties, based on analysis requirements:
    • Finite Element Magnetic Vector Potential:
      1. Specify the Magnetic Vector Potential solver properties (see FE Magnetic Vector Potential Solver). By default, Simcenter STAR-CCM+ solves for the magnetic vector potential using a direct solver which, for large cases, can have large memory and time requirements. To compute the solution using an iterative approach, set Solver Method to Iterative. The available solver options are described in FE Magnetic Vector Potential Solver, FE 稀疏直接求解器参考, and FE Iterative Solver Reference.
    • Finite Volume Magnetic Vector Potential:
      1. Specify the Magnetic Vector Potential and the AMG Linear Solver properties. The available solver options are described in Magnetic Vector Potential Solver.
      2. For the Magnetic Vector Potential solver, set Formulation to either Non-Conservative or Conservative (see Magnetic Vector Potential Solver). When using the Non-Conservative approach, it is recommended that you also activate the Magnetic Vector Potential Projection model, especially in simulations that include eddy currents.
  4. Run the simulation using a double-precision version of Simcenter STAR-CCM+.
