Special solutions are employed permitting one to obtain satisfactory results with rather simple native code. As a test case, $^2\\Pi_u$ and $^2\\Pi_g$ states of H$_2^+$ ions under spherical confinement are considered. The results are interpreted using the correlation of H$_2^+$ states to atomic orbitals of H atoms lying on the confining surface and perturbation calculations.
