MODELLING OF FIELD PROBLEMS IN MATLAB

Modelling by using MATLAB Partial differential equation (PDE) Toolbox is proposed. This toolbox contains the three types of partial differential equations (elliptic, parabolic and hyperbolic equation) that are used as the mathematical models for a wide variety of phenomena in all branches of engineering and science. As examples of the field problems two types of problems were used. The first one is a problem in magnetostatics ? the distribution of magnetic field in an element of magnetoelastic sensor. The second one is a problem of plane stress in structural mechanics - the distribution of stress field in an element of magnetoelastic sensor. The components of magnetic field as well as the components of stress field were carried out by a numerical solution of responding boundary?value problems.
