Assigning Cylindrical Gap Treatment
The Cylindrical Gap operation only works for the TAU (tolerant) mesher. It is a specific mesh operation assigned to the “Band” object for a rotational transient simulation.
While you can select any object and assign the Cylindrical Gap operation to it in any Maxwell simulation, the Cylindrical Gap operation is effective only for rotational transient simulations for which cases the TAU mesher will be chosen as the default mesher; or for which you have manually selected the TAU mesher.
The TAU mesher analyzes the “Band” object, calculates the surface normal angle for the band rotational surface, and automatically assigns the desired mesh operation; or adjusts the existing mesh operations to the adjacent true surfaces at both static and moving sides to ensure a smooth and uniform mesh for the “Band” mesh.
If the CylindricalGap mesh operation is assigned to a regular object, TAU analysis finds the object is not suitable for transient mesh, in which case the regular TAU mesh will be applied. A warning message is then displayed in the message window.
- Select the object you want Maxwell to refine.
-
Click Maxwell 3D > Mesh > Assign Mesh Operation > Cylindrical Gap Treatment or Maxwell > Mesh > Assign Mesh Operation > Cylindrical Gap Treatment.
Note: For 2D transient simulations of rotational models only, refer to TAU2D: Band Mapping Angle Mesh.A Cylindrical Gap mesh operation is applied to the selected object, and a Cylindrical Gap icon appears in the Project Manager Mesh folder.
Note:- There can be only one cylindrical gap operation per design.
- The operation cannot be assigned to multiple objects.
- If you wish to change the name of the mesh operation, you can double-click on the Cylindrical Gap icon to open the Cylindrical Gap Mesh Operation dialog box in which you can type a name for the mesh operation in the Name box.
- Optionally, for 3D transient simulations of rotational
models only, if
you wish to apply a clone mesh operation, check Clone Mesh. This option is unchecked
by default.
When Clone Mesh is selected, the Band Mapping Angle setting is enabled. The valid range of angles is 0.1 through 3.0 degrees, inclusive. The default band mapping angle is 3 degrees. (For more information on this setting, refer to Band Mapping Angle.)
Note: If the model is not suitable to make a clone mesh or the clone mesh process fails, Maxwell automatically falls back to the regular TAU 3D mesher. Because the clone mesh is generated in the initial mesh, the initial mesh is deleted and regenerated once this option is changed and you click OK.
When Clone Mesh is selected, the Number of Layers setting is enabled. You can input the number of mesh layers on the Moving Side and Static Side, respectively. The valid ranges for these settings are integers ≥ 1. The default values are 1. (For more information on this setting, refer to Layers in Band Mesh.)
