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.
- The constraint cannot be oriented other then using the main Cartesian components. This is a limitation of Elmer.
In the most simple analyses, it is not necessary to specify the initial flow velocity, however it is recommended as best practice.
