The conditions for thermonuclear targets ignition in the designed plants of heavy-ion thermonuclear fusion are studied using numerical simulations within the framework of multidimensional multitempetature hydrodynamics. A new scheme of cylindrical target is considered as an alternate variant for radiative targets of "Hohlraum" type using a heavy ion beam in the Fast-Ignition regime.
    It is found that a TD target ignition necessitates a high power supply J_m410⁶ TWt/g, which is achieved by the use of the ions with the energy e_i = 100 GeV. The total energy of the igniting beam is E_ign ~ 0,4 MJ. The propagation of a thermonuclear burning wave from an initiating area provides the thermonuclear gain G_DT 100 with the total energy E_o ~ 5 MJ of a driver for compression and ignition.
    A description is given of the new numerical MDMT method whereby the results were gained.
