  The Code O-SUKI-N 3D is an upgraded version of the 2D Code O-SUKI (Comput.
Phys. Commun. 240, 83 (2019)). Code O-SUKI-N 3D is an integrated 3-dimensional
(3D) simulation program system for fuel implosion, ignition and burning of a
direct-drive nuclear-fusion pellet in heavy ion beam (HIB) inertial confinement
fusion (HIF).The Code O-SUKI-N 3D consists of the three programs of Lagrangian
fluid implosion program, data conversion program, and Euler fluid implosion,
ignition and burning program. The Code O-SUKI-N 3D can also couple with the HIB
illumination and energy deposition program of OK3 (Comput. Phys. Commun. 181,
1332 (2010)). The spherical target implosion 3D behavior is computed by the 3D
Lagrangian fluid code until the time just before the void closure of the fuel
implosion. After that, all the data by the Lagrangian implosion code are
converted to the data for the 3D Eulerian code. In the 3D Euler code, the DT
fuel compression at the stagnation, ignition and burning are computed. The Code
O-SUKI-N 3D simulation system provides a capability to compute and to study the
HIF target implosion dynamics.
