Question

who is Boolean in the electronic field

Answer 1

Example: 2 metal spheres in transformer oil, one with voltage, the other is grounded. calculate the electric field.

A. Set up 2 metal spheres and a cylinder as oil--> Form union(last step of geometry)
B. Set up 2 metal spheres and a cylinder as oil--> Boolean Operation(Union) --> Form union(last step of geometry) 
C. Set up 2 metal spheres and a cylinder as oil--> Boolean Operation(Differences 2 spheres from Oil) --> Form union(last step of geometry)

In 2D calculations, A,B,C almost the same result.
In 3D calculations, A,B have the same result, C is almost double than A,B
