FEM ConstraintInitialFlowVelocity/it

Description
Da fare

Usage

 * 1) Click on [[Image:Fem-constraint-initial-flow-velocity.svg|32x32px]] or choose Model → Fluid Constraints  →   from the top menu.
 * 2) 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.
