The application of finite element methods to parabolic partial differential equations leads to large linear systems of first-order ordinary differential equations. Very often these systems are stiff and difficulties arise in their numerical solution. We attempt to analyse the problem of how to selec

✦ Synopsis
A time-dependent Hartreegrid wavepacket propagation method (in which each degree offreedom 1s represented by a numerical grid, and evolved according to one-dimensional mean field equations) is successfully utilized to calculate S-matrix elements for collinear atom-Morse oscillator scattering. The possibility of developing a convergeable contiguration-interaction scheme based upon zeroth-order time-dependent Hastree evolution is briefly discussed.
