The Y Wires examples consists in studing 3 wires in an Y shape.
The length of the wire is 10 micron wheras the diameter of the wires is 2.5 micron. The angle between wires is about 120 degrees.
The mesh constains 128 cells in X direction, 128 cells in Y direction & 16 cells in Z-direction. The cells of the mesh are not cubic 0.14x0.13x0.16 micron^3.
The anisotropy direction U1 is uniformly in the X-direction with an uniaxial crystal type.
The initial magnetism M is uniformly in the X directon.
The external magnetism field is set to null.

| initial magnetism value | neighbors indicators | first anisotropy directions |
The matter parameters are as follow :
| Ms | Aimantations (A/m) | 1.7e6 |
| K1 | First Anisotropy (J/m^3) | 1.e4 |
| K3 | Secund Anisotropy (J/m^3) | 0 |
| A | Exchange (J/m^3) | 1.e-9 |
The relaxation technics converge with 2100 iterations to reach the relaxation rate.
The value of magnetism field at equilibrium state are plot as follow:
 |
 |
 |
| equilibrium magnetism value along x | equilibrium magnetism value along y | equilibrium magnetism value along z |
 |
 |
| equilibrium magnetism vector with total magnetism module | equilibrium total magnetism field norm |
The simulation with different configuration of exchange coefficient are given as follow:
 |
 |
 |
| A=1.e-8 | A=1.e-7 | A=1.e-6 |
