Due to symmetry about X-axis, lower part of the model can be removed (including all semicircles below the X-axis).

Then we have to reflect the removed part by means of boundary condition on the X-axis:

HX=0 dA/dy = 0,

i.e. dA/dn = 0

Name all important geometry entities

In order to assign materials, field sources and boundary conditions, we have to give unique names to:

1.All blocks, including:

a)Steel cylinder,

b)Left wire

c)Right wire

d)Surrounding air

2.Outer edges, including:

a)Symmetry axis

b)Artificial outer boundary
