Hello,

I am attempting to model photon diffusion using Helmholtz equations in 4.1. I have a tutorial from 3.5 which used a scalar times u_test (which i believe is the delta function) on my point source. However, u_test does not seem to be a function incorporated into 4.1. Is there a comparable function in 4.1?

Thanks,
Nicholas
