Difference between defining one weak contribution at several points or several weak contributions with each located at one point

Hi Comsol community,

I would like to introduce point sources in equation based simulation. In the simulations the PDE of the system is defined with the help of the weak form. Now I would like to introduce 10 point sources and in principal there are two ways:

1.) Defining one weak contribution and select all 10 points

or

2.) Defining 10 weak contributions, each of them only at one point

Is there a difference between the two methods. And in case that there is a difference, which way is preferable

Thanks a lot in advance,
Felix
