Introduction to the Multiscale Finite Element Method MSFEM:
If we compare a Large scale (transformer core with overall dimensions) to a Fine scale (thickness of the laminate d and width of the air gap d 0)
The geometric dimensions are extremely different: two scales
The laminated core represents a quasi periodic structure with period p =
