A non-trivial approach for low-frequency magnetic field simulation and visualization

The article presents a program decision that is intended to assist engineers and medical specialists to design and apply electromagnetic devices for therapeutic purposes. The suggested approach for the problem solving is non-trivial because it combines the power of the existing graphics package with the possibilities of a new code for electromagnetic calculations. The presented program decision demonstrates precise numerical results complemented by an understandable and attractive graphical representation. The implemented approach allows a high level of interaction during the whole process that includes: selection of a 3D model of human body part, creation and positioning of field sources, calculation and visualization of the summary field.
