Introduction
Верстак МКЭ предоставляет современный набор инструментов для анализа Методом Конечных Элементов в FreeCAD. В основном это значит объединение в одном GUI всех инструментов для выполнения анализа Методом Конечных Элементов.
Workflow
Шаги которые необходимо сделать чтобы произвести расчет МКЭ в GUI верстака FEM FreeCAD:
- Препроцессор
- Моделирование геометрии, здесь FreeCAD уже является вполне развитым приложением.
- Создать Расчет:
- Создать Сетку МКЭ из геометрической модели.
- Добавить Условия, такие как нагрузки и фиксаторы к расчетной модели.
- Добавить в расчетную модель Материал
- Решение уравнений
- Решение системы уравнений из FreeCAD GUI.
- Постпроцессор
- Посмотреть в FreeCAD GUI Результаты.
В версиях 0.15 и 0,16 FreeCAD модуль FEM может использовать платформы Windows, Mac OSX и Linux. Поскольку верстак FEM использует внешние программы, многие ручные настройки, требуемые для того, чтобы верстак FEM стал готов к использованию, зависит от используемой Вами операционной системы. Смотрите FEM Install.
