Imposing pumping well in 2D model

Hi comsolers,

I want to impose pumping well in 2D model NOT 2D axisymmetric .
Is there any way to impose well, if yes which boundary condition should I define that comsol knows that in my model I have a well?

and I know that I should also consider the thickness of the well, radius of the well,....

Any help or answer is appreciated.
Thanks
