Electrical Connectivity When Combining Geometry

Geometry parts need to physically connect to ensure electrical connectivity once the model is meshed (except when using FDTD). Use the union, stitch or imprint operation to ensure electrical connectivity.

The simulated model has electrical connectivity as long as the mesh elements align and do not intersect. This results in the correct basis functions being created for the simulation. The following operations allow for geometry parts to be physically connected by ensuring that the resulting mesh elements align correctly:
This operation is used to physically connect geometry parts. This is the default and most common operator used in CADFEKO.
This operation is used to physically connect imported sheet parts where geometry is unconnected or have small sections that overlap. The stitch operation is generally faster than the union operation.
Imprint points
This option allows you to specify points and projecting the points onto the closest point of the selected geometry part, either on a face or on an edge. The imprinted points are considered when meshing the model. Snap to the imprinted points to create physically connected geometry. Imprinting points is especially useful when connecting wires to faces when you do not want to union the wire onto the face.
