For the numerical calculation of the magnetic field and forces between high temperature superconducting (HTSC) materials and permanent magnets (PM) an algorithm and a 2D finite difference computer code has been developed. The superconductor has been treated with its nonlinear dc magnetization curve. The model incorporates also anisotropic HTSC materials with different magnetization characteristics along the coordinate axes. The magnetization curves are used as input characteristics for the field calculations. The calculations may be carried out both in the Cartesian and the cylindrical coordinate systems. The HTSC and PM parts or elements may have arbitrary shapes within the limits of the accuracy of the finite difference rnesh. The model includes both the field-cooled and zerofield-cooled cases. The code is capable of simulating the movement of either of the objects.
