Summary for: SlidingAirgap < SlidingAirgapBase

Class summary

SlidingAirgap Sliding airgap model for radial-flux machines.

The number of airgap layers can be set on the model level by setting dimensions.number_of_airgap_layers

Alternatively, gap-specific arguments can be delivered by setting a structure airgap_arguments into this.static_component.dimensions, with the following optional fields:

• number_of_airgap_layers : Overrides the above, if given.
• cutoff_layer : Essentially, the number of layers on the moving-component side. Must be 1 < cutoff_layer < number_of_airgap_layers. Defaults to number_of_airgap_layers - 1. is_conforming : Do the moving- and fixed-side meshes conform on the interface? Defaults to true. If false, a duplicate interface layer of nodes is added to the root model mesh, with the moving-side nodes added as flux-insulation (Dirichlet) nodes, due to how the sliding interface is handled.
• Note: second-order tris may sometimes suffer from nonphysical ripple in this case. A non-conforming mesh can help.
