The multi-mode approximation is presented to compute the interior wave function of Schrodinger equation. This idea is necessary to handle the multi-barrier and high dimensional resonant tunneling problems where multiple eigenvalues are considered. The accuracy and efficiency of this algorithm is demonstrated via several numerical examples.AMS subject classifications: 35C99, 65N99, 81Q05
