Hello,
Very beginner in Comsol. I would like to model an LED light source in Comsol. I understand I can safely model it as an isotropic light source. I was just wondering if Comsol has any built in point light source I could use.

Thank you

Hi

I believe not as an electromagnetic RF light beam, but if you consider "illumination" as incoherent sources and fluxes with straight propagation you could do something but you must write your own equations I believe. Or perhaps by similarity with some other physics

Good luck

I think it is possible with Helmholtz equation.
