Описание
Создает ограничение начальной скорости потока для анализа потока жидкости.
Применение
- Press the Initial flow velocity condition button or select the menu Model → Fluid boundary conditions → Initial flow velocity condition.
- Enter an initial flow velocity value for the analysis. The value is entered as a combination of the 3 main cartesian vectors components (X,Y,Z).
- For a 3D analysis, select a 'solid' (body) from your model, for a 2D analysis select a face. However, it is also possible to select a face (e.g. the inlet of a pipe) in 3D or an edge in 2D.
Formulas
For a description how to input formulas, see section Formulas in the page for the Flow velocity constraint.
Примечания
В самых простых анализах нет необходимости указывать начальную скорость потока, однако это рекомендуется в порядке хорошего стиля работы.
