Helmholtz equation:##\nabla^2 u=-ku## is the same form of ##\nabla^2 u=f##.
So is helmholtz equation a form of Poisson Equation?

I think you mean when f = -kuThanks for the reply, I understand the difference between the two. But Helmholtz is also in form of Poisson, only when ##f=-k\nabla^2 u##. So, can I say Helmholtz is a subset or one form of Poission Equation?
Thanks
Yes, my bad. What is FWIW?I think you mean when f = -ku
FWIW, sure, go ahead.
