Описание
Создает ограничение начальной скорости потока для анализа потока жидкости.
The FEM initial flow velocity task panel
Применение
- There are several ways to invoke the command:
- Press the
Initial Flow Velocity Condition button. - Select the Model → Fluid Boundary Conditions → Initial Flow Velocity Condition option from the menu.
- Press the
- 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).
- Press the Add button. 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. introduced in 1.1: To remove objects from the selection, press the Remove button.
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.
