Начались поставки пользователям пакета CST STUDIO SUITE 2006 Опции

[Yuri Potapoff]

Уважаемые господа!

Компания CST (www.cst.com) начала поставки пользователям новой версии
набора своих продуктов для полного трехмерного моделирования во
временной и частотной области CST STUDIO SUITE 2006.



В основе пакета лежит универсальная среда разработчика CST DESIGN
ENVIRONMENT, являющаяся дальнейшим развитием пакет CST MICROWAVE
STUDIO.

В версию CST MICROWAVE STUDIO 2006 добавлены следующие функции:

- Интегрированная среда CST DESIGN ENVIRONMENT позволяет просмотр как
трехмерного, так и схемотехнического представления анализируемых
моделей. Базовая лицензия CST MWS включает возможность моделирования
схемы из сосредоточенных RLC элементов совместно с 3D EM структурами.

- Доработан механизм тетраэдрального разбиения при использования
вычислительного ядра в частотной области. Теперь разбиение более
качественно повторяет контуры поверхностей анализируемых объектов,
учитываются граничные условия с поглощением, введена поддержка поля в
дальней зоне, гиротропных сред, сосредоточенных элементов, ячеек
произвольной формы, адаптивного разбиения, адаптивного алгоритма
частотного свипирования.

- Значительно усовершенствованы средства интеграции с пакетом Advanced
Design System (ADS) компании Agilent Technologies.

- Доработан интерфейс с пакетом Allegro компании Cadence.

- Разработан новый алгоритм учета идеальных граничных условий PBA при
гексаэдральном разбиении.

- Введен учет дисперсионных свойств материалов, которые могут быть
описаны в табличном виде. Это дает возможность описывать модель
человеческого тела.

- Поддержка моделей проволочных перемычек по стандарту JEDEC.

- Усовершенствован механизм распределенных вычислений в рамках
локальной сети. Новая схема позволяет минимизировать обмен данными
между компьютерами и снизить сетевую погрешность.

- Введены новые средства постобработки результатов расчета:
характеристики в дальней зоне над заземляющей поверхностью с потерями,
новый механизм экстракции SPICE схемы замещения, осредненные
зависимости для различения полей с линейной и круговой поляризацией.

В пакет CST STUDIO SUITE 2006 вошли:

- CST MICROWAVE STUDIO для моделирования СВЧ структур.

- CST EM STUDIO для моделирования низкочастотных и статических полей.

- CST PARTICLE STUDIO для моделирования поведения заряженных частиц в
электромагнитных полях.

- CST DESIGN STUDIO для синтеза и моделирования схемотехнического
представления проектов.

Все программы интегрированы в рамках единой среды CST DESIGN
ENVIRONMENT, обеспечивающей взаимодействие и учет различных физических
эффектов.
