FEM ConstraintInitialFlowVelocity/pl

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

Usage

 * 1) There are several ways to invoke the command:
 * 2) * Press the button.
 * 3) * Select the option from the menu.
 * 4) Enter an initial flow velocity value for the analysis.
 * 5) 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.
