Beschreibung
Erstellt eine Randbedingung für den Startwert eines Druckes für die Strömungsanalyse eines Fluids.
Anwendung
- Either press the toolbar button FEM ConstraintInitialPressure or select the menu Model → Fluid Constraints → Constraint initial pressure.
- Enter an initial pressure value.
- For a 3D analysis, select a 'solid' (body) from your model, for a 2D analysis select a face.
Hinweise
For simple analyses, it is not necessary to specify the initial pressure, however also in these cases it is recommended as best practice.
