Calculation adopted to calculate values is FDM(finite difference method). Grid and limited nodes are used to simulate the whole magnet while the effect of excessive layer is simplified as the function of the limited nodes on both sides of the interface. Thus the constant, whose unit is the same to the one of the exchange constant in block,plays its role in computational process among joints only which is not a breach of the specific physical image.

The constant functions only in the calculation of nodes, with the same unit as that of block exchange constant and so not breaching the specific physical image, since the calculation is finite difference method and uses grids and limited nodes to simulate the whole magnet, simplifying the effect of excessive layer into that of the limited nodes on both sides of the interface.

Because the calculation method on the numerical calculation with the finite difference method and grid and limited number of nodes to simulate the whole magnet, simplified interface on both sides of the limited impact of excessive layers of nodes, so this constant only between nodes during calculation work, units and blocks have the same Exchange constants, units, and not contrary to the specific physical image.
