FEM ConstraintInitialFlowVelocity

Description
Creates an initial flow velocity constraint for a fluid flow analysis.

Usage

 * 1) Either press the toolbar button  or select the 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).
 * 3) 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.
