Creating a Maxwell Design from RMxprt

RMxprt provides a way to export solved models as either a Maxwell 2D or Maxwell 3D design.

Note: Creating a Maxwell 2D/3D design from an old version (version 15 or older) of a solved RMxprt design results in the Maxwell 2D/3D design being created without any variables even if the original RMxprt design uses variables. In such cases, the Message Manager displays a warning message informing the user that the Maxwell design being created does not contain any variable assignments from the RMxprt design; and recommends re-solving the setup to get the variable assignments.

To export the model to a Maxwell 2D Design or Maxwell 3D Design:

  1. Click RMxprt > Analysis Setup > Create Maxwell Design

The Create Maxwell Design dialog box appears.

  1. Select one of the following from the Type drop-down menu:
  1. Select the setup you want to export from the Solution Setup drop-down menu.
  2. Optionally, click the [...] button to specify a Variation in the Set Design Variation dialog box. This allows the user to choose the default variable values to be used in the Maxwell design being created with variables.
  3. Click OK to create the Maxwell design.

You can now work with the model in the Maxwell 2D or Maxwell 3D design, add boundaries and excitations, perform analyses, and analyze results.

Note:  
  • For Maxwell 2D/3D designs for motor applications, the computed output mechanical power at a given constant speed may not reach the desired rated power. Therefore, it is useful to apply constant power as the mechanical load. In Maxwell 2D/3D designs created by RMxprt, the mechanical transient is setup according to the rated mechanical output power, and equivalent damping is added to accelerate the process approaching to the rated output power. This setup is visible when Consider Mechanical Transient on the Mechanical tab of the Motion Setup dialog box is checked.
  • For Maxwell 2D/3D designs of AC machines, RMxprt automatically enables an alternating flux (AF) model in the voltage definition for each winding to reduce transient solution time to reach steady-state when the Maxwell 2D or 3D model is created.
  • For Maxwell 2D designs of double-cage induction machines with separate end rings, and of synchronous machines with separate dampers for each pole, RMxprt automatically creates multiple end connection excitations in the Maxwell 2D design. For synchronous machines, if the created geometry model has only one pole, it is changed to two poles, with two separate end connection excitations. This enables simulation of double-cage induction machines with separate rings, as well as synchronous machines with separate dampers for each pole.
