    Answer ✓

    You can convert your Real and Imaginary values into Magnitude and Phase angle. Those two quantities can be applied in the form of a vector load using the following example:

    rf = analysis.AddRemoteForce()
# Scope the result object to the desired body
…
Im = 3.
Re = 4.
resultant = sqrt(Im**2 + Re**2)
rf.DefineBy = LoadDefineBy.Vector
rf.Magnitude.Output.DiscreteValues = [Quantity("%s [N]" % resultant)]
phase = atan(Im / Re) * 180 / pi
rf.PhaseAngle.Output.DiscreteValues = [Quantity("%s [deg]" % phase)]
# If for example the force is applied in the Global Z-Axis
rf.Direction = Vector3D(0, 0, 1)
