- GuiCommand: Name: FEM ConstraintInitialFlowVelocity MenuLocation: Model -> Fluid Constraints -> Constraint initial flow velocity Workbenches: FEM_Workbench SeeAlso: FEM_ConstraintFlowVelocity, FEM_ConstraintInitialPressure
Creates an initial flow velocity constraint for a fluid flow analysis.
- Either press the toolbar button
'''FEM ConstraintInitialFlowVelocity''' or select the menu Model → Fluid Constraints → Constraint initial flow velocity. - 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.
For a description how to input formulas, see section Formulas in the page for the Flow velocity constraint.
In simple analyses, it is not necessary to specify the initial flow velocity, however it is recommended as best practice.
