The package includes a graphical preprocessor,
a solver, and a graphical postprocessor:
The preprocessor allows the user to draw
parts, specify materials, and so on. DXF drawings can be imported into
the preprocessor
(although not all entities are currently
supported).
Currently, the solver addresses 2-D planar
and axisymmetric magnetic problems (including linear and nonlinear magnetostatic
problems and low frequency harmonic problems).
Nonlinear problems are solved using a Newton iteration. All matrix inversions
are
performed by a Conjugate Gradient solver
using a Symmetric Successive Over-Relaxation (SSOR) preconditioner.
The graphical postprocessor allows the
user to examine and manipulate the solution. The contour and density plot
renderings of the
solutions are available. Plotting of various
field quantities along user-specified coutours is supported. A number of
integrals along
user-defined contours and volumes are
also supported.
There is no hard limit on problem size--maximum
problem size is limited by the amount of available memory.
