3. NATURE OF PHYSICAL PROBLEM SOLVED

HEDO-2 allows calculation of the magnetic field, magnetic volume forces, and the self and mutual inductance coefficients of arbitrary air-core coil systems. In addition, the program is suitable for the calculation and graphic representation of field and contour lines (lines B = const).

4. METHOD OF SOLUTION

Approximation of the spatially distributed currents by line currents, in which the number of closed line currents per coil can be freely chosen in accordance with the calculating accuracy required. All types of calculations possible with HEDO-2 are based on the field representation of line currents.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

(a) The coils must have rectangular winding cross sections.
(b) The contour of each coil must be symmetric to at least one coordinate axis.
(c) The function describing the contour and the derivative of the function must be continuous.
(d) Maximum number of coils n=200
(e) Maximum number of test points p=2000
(f) Test points ought not to be located on a line conductor.

6. TYPICAL RUNNING TIME: 0.04 sec. per coil and test point.
