(RWR) « lessĪ numerical study is made of a problem dealing with calculation of the magnetic field B vector, the magnetic vector potential A vector, and first partial derivatives of the B vector field and A vector components for two kinds of magnetic sources: (1) current-carrying straight wire of finite length and (2) current-carrying closed polygon. On field contour and flux line plots, lines of intersection between the coils and the plotting plane are also shown. Plots of field contours, field profiles, flux lines, field magnitude along a flux line, and forces can all be obtained at the option of the user. In addition, each column of numbers on each page is appropriately labeled.
Each page of output is labeled with the problem title the time, machine and data of the run and the version number and compile date for EFFI. EFFI produces both printed and graphical output. If no errors are detected, the program automatically expands memory to the size required for the problem. To aid the user in correcting mistakes, each error detected produces a diagnostic giving the objection to the data and the number of more » the offending data card.
All input to EFFI is format free, and is checked for validity before any calculations are done.
Several examples, including the magnet design for MFTF and a divertor design for a Tokamak are used for illustration.
#Vector fashion ih5 code
The preparation of input to the code and the output options available are described. = ,ĮFFI calculates magnetic flux lines, fields, forces, and inductance for an arbitrary system of coils made from circular arc and/or straight segments of rectangular cross section conductor.
