This is the main MCTDH-X program. MCTDH-X is a program package to solve the time-dependent many-body Schroedinger equation for indistinguishable particles. The theory expands the field operator in time-dependent modes. Hence, MCTDH-X provides a way to systematically improve the predictive quality of the numerical description beyond mean-field methods like the discrete non-linear Schroedinger equation, the Gross-Pitaevskii equation, or Hartree-Fock approaches. The main program runs the initialization of variables and arrays and starts the Master and Slave processes that drive the 7-step integration scheme (see PRA 77 033613).
