How to Use a Maxwell 2D or 3D Finite Element Model in Twin Builder

The following steps outline the process for preparing and using a Maxwell 2D or 3D Finite Element model in Twin Builder.

  1. Create a model of the component in Maxwell 2D or 3D Transient, including the geometry, a moving band, materials, boundary conditions, external windings, and mesh.
  2. Solve the problem in Maxwell to ensure that the Maxwell 2D or 3D Transient project is set up correctly. Errors in the Maxwell project cannot be corrected from Twin Builder.
    Note:
    • See the Maxwell documentation for detailed information on creating and solving the Maxwell 2D or 3D model.
    • This preliminary Maxwell solution need not be for the same conditions or ending time that Twin Builder will establish.
  3. Ensure that Twin Builder has run-time access to Maxwell, either on the same computer, or another computer on the network via TCP/IP.
  4. Establish a link to the Maxwell 2D or 3D Transient project, and place a Maxwell Transient Cosimulation Component on the Twin Builder schematic.
  5. Connect electrical and mechanical pins of the Maxwell Transient Cosimulation component to other models on the Twin Builder schematic.
  6. Select a Transient Analysis Setup for the simulation. Attempting to simulate using either AC and DC analysis setups will fail setup with resulting error messages in the Message Manager.
  7. Run the simulation in Twin Builder.

Maxwell 2D or 3D Transient will start in a co-simulation mode.
