Does the new version supersede the previous version?: Yes

Nature of problem:
Simulation of dynamical solutions for a class of systems (multi-components) of time-dependent Gross-Pitaevskii equations in 1d, 2d and 3d. This program is particularly well designed for the simulation of the dynamics of Bose-Einstein condensates as well as the computation of ground states.

Solution method:
We use spectral schemes in space and splitting/relaxation scheme in time.

Reasons for new version:
To include dynamicsimulations.

Summary of revisions:
It is now possible to do dynamical simulationswith the code.

Running time:
From a few seconds for simple problems to a few minutes for more complex situations on a medium computer.
