1-dimensional stationary PDE analysis - which form is appropriate?

Please login with a confirmed email address before reporting spam

Hello,

I am a new user of COMSOL and am trying to determine the best PDE mode and an approach to solving the following problem:

(∂^2/∂x^2) u(t, x) - u(t, x) = - i(t, x)

where u(t,x) = 0.5*e^(-|x|)

i(t,x) = δ(x) localized at x = 0.

Boundary conditions should be u(+infinity) = 0 and u(-infinity) = 0.

Any pointers in the right direction would be greatly appreciated. Thank you!
