spherical harmonic source

I have a 3D beam model in the frequency domain. I am trying to impose a harmonic spherical source. A point load that acts as a spherical harmonic source. I am not sure how I can do this.

I defined a spherical coordinate system; however, when I assign a point load in that coordinate. It is merely a directional load.

What I need is spherical source that applies load along radial direction in all angles.

Also is it possible to prescribe a harmonic displacement rather than harmonic load.

Thanks
