The multi-layer coating mesh function automatically generates a layered mesh on the surface of a region in a 2D analysis. It is used when accounting for magnetic or non-magnetic thin films (coatings) that coats wires.
Regardless of the cross-section geometry (round, square, stranded, etc.), the mesh is generated with a uniform thickness for each wire.
Furthermore, material properties can be set for each layer.
This script sets two layers of multi-layer coating mesh and the material properties for each layer.
Preconditions
- One or more 2D analysis study has been created.
This script runs on the active magnetic field analysis study in the project tree. - Materials to be set for coating layers have been registered in the study.
- The part set for setting the multi-layer coating has been created and its title is known.
Script Function
- Set the multi-layer coating to the part set named "CoilSet".
- Set two coating layers (layer names are Group 1 and Group 2 from the outer side).
- Set the parameters for each coating layer.
Group 1
Thickness: 0.01
Material: Copper
Mesh divisions: 5
Group 2
Thickness: 0.005
Material: TRANSFORMER_FILM
Mesh divisions: 2 - Set the eddy currents of the Group1 layer: Copper to be allowed.
