Export Transient/Harmonic Force from Maxwell

There are four options to export transient forces and one option to export transient/harmonic force from Maxwell transient solvers:

• LMS – provides element-based transient surface node force and mesh to link to Virtual lab, only for stator of electric machine.
• Romax – provides object-based transient force for the stator of electric machines and torque information.
• UNV – UNV file format is a standard universal file format, and it can be read by most of third-party software. Element-based transient surface/volumetric node force will be outputted with mesh.
• Ansys Motion – provides object-based transient force, and element-based surface transient force to Ansys-Motion for structure and acoustic simulation.
  Note: Ansys Motion does not currently support harmonic force.

• Ansys Mechanical

  • For 3D transient solver, if Element Based (Volumetric) harmonic force selected, this option provides element-based volumetric harmonic force in .csv file format to Ansys-Harmonic Response for acoustic simulation.
  • If Object Based harmonic force is selected, this option provides object-based harmonic force with RPM parametric sweep to generate waterfall diagram in Ansys Mechanical.

All forces and mesh are output with the full model. To export transient/harmonic force from Maxwell, following steps must be done before solving the design:

1. Either select Maxwell 2D (or Maxwell 3D) > Enable Harmonic Force Calculation, or right-click on the design in the Project Manager tree and select Enable Harmonic Force Calculation to open the Enable Harmonic Force Dialog window.

   

2. On the General tab, select the Force Dependent objects for which force calculations are desired. For LMS, select only one object (stator).
3. Select Type of force for output. Choices are: Object Based, Element Based (Surface), or Element Based (Volumetric).
4. Check Transient Force if you want to export transient forces. (Harmonic Force is for Workbench Harmonic Response Coupling.)
5. Check Harmonic Force if you want to export element-based volumetric harmonic force in .csv file format. This export option is only available for the Maxwell 3D magnetic transient solver.
   Note: Both Transient Force and Harmonic Force can be exported; check both options to export them for the same simulation.

After solving the design, select Maxwell 2D (or Maxwell 3D) > Export Transient/Harmonic Force to generate transient forces.
