How can I transfer an RmXprt model to Maxwell 2D or 3D for FEA simulation?

This article explains the process of exporting an electric motor model designed in Ansys RmXprt to Maxwell 2D or 3D for finite-element analysis.

After completing your motor design in RmXprt using the available templates, create an analysis setup. Right-click Setup1 and select Analyze to ensure the model runs without errors.  

Once the analysis completes successfully, you can view the performance results by right-clicking Setup1 and selecting Design Sheet. 

To transfer the design to Maxwell: 

• Right-click Setup1 again and choose Create Maxwell Design… 

• In the dialog box, select Maxwell 2D or Maxwell 3D, ensure Setup1 is selected, and click OK 

If the transfer option is disabled, confirm that the analysis has been completed successfully and no errors are present in the Message Manager. 

The new Maxwell project will be generated automatically, including all material assignments, excitations, and circuit connections (if defined in RmXprt). 

For Maxwell 2D, the design is ready to run but typically needs finer meshing, adjusted time step, and a defined stop time.

If you choose Maxwell 3D Design from the pop-up window. 

For Maxwell 3D, a fractional 3D segment of the motor is created with all relevant boundary conditions and excitations assigned.
