15.5.8. forceNorm

Returns the per unit width force on a line in the direction of the specified axis. It is available only for a polyline created by intersecting a locator on a boundary. Momentum data must also be available. The magnitude of the value returned can be thought of as the force in the specified direction on a polyline, if the polyline were 2D with a width of one unit.

[<Phase>.]forceNorm[_<Axis>[_<Coord Frame>] ]()@<Location>

where:

  • [<Phase>.] is an optional prefix that is not required for single-phase flows. For details, see CEL Functions with Multiphase Flow.

  • <Axis> is x, y, or z

  • <Coord Frame> is available in CFD-Post only

  • <Location> is any 1D location. An error will be raised if the location specified is not one-dimensional.

forceNorm_y()@Polyline1 calculates the per unit width force in the Y direction on the selected polyline.
