Specific features of numerical simulation of spatial magnetic fields of precision systems

Characteristics of numerical simulation of space magnetostatic fields of the precision magnetic systems and application of a scalar potential are considered. An additional vector is determined in a local subregion of the calculation region; the subregion may be quite arbitrary to satisfy the requirements for increase of calculation accuracy, for simplicity of construction description, for decrease of operation number. The method of finite elements is used to obtain finite-difference equations. The results of numerical simulation of the space field of face parts of the dipole magnet with a complex form of a coil bend are given illustrating calculation accuracy
