Beschreibung
Erstellt eine Startbedingung einer Fließgeschwindigkeit für die Strömungsanalyse einer Flüssigkeit.
Anwendung
- There are several ways to invoke the command:
- Press the FEM ConstraintInitialFlowVelocity button.
- Select the Model → Fluid Constraints → Constraint initial flow velocity option from the menu.
- 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).
Limitations
- The constraint applies the initial flow velocity to all nodes in the FEA model.
- The constraint cannot be oriented other then using the main cartesian components.
Hinweise
In the most simple analyses, it is not necessary to specify the initial flow velocity, however it is recommended as best practice.
