A post-processing graphic package has been developed for the computer animation of 2D as well as 3D electromagnetic fields obtained from various finite element programs available at IGTE. The goal was to use relatively inexpensive and commonly available personal computers (e.g. 486/33 MHz systems or better) for this purpose because they have the further benefit of good transportability, advantageous at scientific conferences or in classrooms.>
