Scattering by a point source dipole

Hi,

I am new COMSOL user and currently using it to model Scattering from a point source dipole.Though ,I am able to simulate the Scattering phenemona from the dipole source ,I have a doubts which is as follows

1 How to vary the position of the point source from one point to other so that scattering data can be taken from multiple points(Dipole point acting as Transmitter) ?

Attached with this is my simulation result .

Regards.
