The method of contracting mapping of the function space is suggested as a tool of spatial approximation of electromagnetic fields. This transformation is physically justified being associated with the dynamics of space field variation. Formulated are the basic requirements for scale transformation of the solution space. Three basic types of contracting mapping are applied to some linear-symmetry VES problems. A special algorithm is suggested for smoothness control of signals and automated filling of the space with additional reference points in intervals of strongly varying field components. The new approach allows high-performance modeling in problems that require high-density recovery of functions.
