Using Patch Meshing

You can mesh the Air, Slot, and Stator Steel parts at the same time using patch meshing. Patch meshing requires you to create patches on the source surface manually. Simcenter STAR-CCM+ uses these patches to generate a quadrilateral surface mesh. The three parts have contacts that are defined between them, allowing them to be used together in one directed mesh operation.

  1. Right-click the Geometry > Operations node and select New > Mesh > Directed Mesh.
  2. In the Create Directed Mesh Operation dialog, select the Air, Slot, and Stator Steel parts.
  3. Click OK.
  4. Right-click the Geometry > Operations > Directed Mesh node and select Edit.
    The Directed Mesh panel that is used for all directed mesh operations appears. Only the selected parts are shown in the Graphics window.

  5. In the Directed Mesh 1 window, select the three target surfaces:
    • Stator Steel.target
    • Slot.target
    • Air.target
  6. Right-click on one of the selections and choose Part Surfaces > Add To Target .


  7. In the Directed Mesh 1 window, select the three source surfaces:
    • Stator Steel.source
    • Slot.source
    • Air.source
  8. Right-click on one of the selections and choose Part Surfaces > Add To Source.


    The source surfaces are grouped together in the Properties of the Directed Mesh > Source Surfaces node and are colored green in the Graphics window. The target surfaces are grouped in the Target Surfaces node and are colored red. The surfaces are shown in the following image with the scene transparency turned on.
