How to Use a Maxwell Equivalent Circuit Model in Twin Builder

The following steps outline the process for preparing and using a Maxwell Equivalent Circuit model in Twin Builder.

1. Create a model of the component in Maxwell, including the geometry, materials, boundary conditions, external windings, and mesh.
2. Solve the problem in Maxwell to ensure that the Maxwell 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 model.
3. Ensure that Twin Builder has runtime access to Maxwell on the same computer or another computer on the network.
4. Establish a link to the Maxwell Equivalent Circuit model project, and place a Maxwell Equivalent Circuit component on the Twin Builder schematic.
5. Connect electrical and mechanical pins of the Maxwell Equivalent Circuit component to other models on the Twin Builder schematic.
   Note:

   Equivalent Circuit models exported from Maxwell that have mechanical pins must be connected by these pins to a mechanical subsystem having a ROTATIONAL_V nature. For versions of Maxwell lower than Version 10, Service Pack 1, this must be done using a Domain to Domain component. For later versions, the connection can be made directly.

6. Run the simulation in Twin Builder.
7. Switch back to Maxwell if you need to update the model design.
