VectorUnit_j
The VectorUnit_j function takes no parameters. It returns the j-unit vector, e.g., (0,1,0). The vector to which the unit vector is assigned must have previously been defined with the $Vector or $Vector2D directive.
VectorUnit_j may be followed by multiplication/division with a scalar or addition/subtraction of a vector.
Example:
$Vector Y
Y=VectorUnit_j*(3 [kN])
{Solution:
Y = (0, 3, 0) [kN]
}
