MCTDH software maintained by H.-D. Meyer's group in Heidelberg: The acronym stands for Multi Configuration Time Dependent Hartree. It is designed for multi-dimensional problems, i.e. for problems that are difficult or even impossible to attack in a conventional way. In particular, the multi-layer extension of MCTDH has been used for problems involving hundreds of degrees of freedom!
