    Graduate Have a software that solves Helmholtz equation, can I use it for Poisson?

    Thank you again SteamKing, I understand that, however if I need to solve a Poisson equation (with non zero RHS) wouldn't making lambda = 0 not be it?

    Thank you Steamking, my issue is if lambda is zero, wouldn't that reduce to Laplace instead of Poisson? Thanks again

    Graduate Have a software that solves Helmholtz equation, can I use it for Poisson?

    I only took one class of PDE and even though I do remember the relationship between Laplace and Poisson I really do not recall Helmholtz at all. Anyways, I am trying to figure out if my software (a software I found online, FISKPACK) that solves Helmholtz equation can be used to solve Poisson...
