"""Самостоятельное полевое исследование во встроенном Python FEMM 5.

Все размеры геометрии указаны в миллиметрах, результаты — в СИ. Значения
гармонических токов являются амплитудами. Материалы и условия имеют русские
имена; номера групп описаны в README. Программа создаёт новую calculated-NN
рядом с собой, не заменяя предшествующих расчётов. Каждая входная модель
сохраняется, закрывается, открывается повторно и только затем решается.
Открытые пользовательские документы не изменяются. Параметры — в CONFIG.
