A PC code based on the quantum mechanical Langevin equation to simulate dynamic motion of deuterium (or hydrogen) cluster with three dimensional symmetry has been developed for studying very fast condensation or oscillation behavior in time-step of 0.001 as (1.0E-21 second) for overall time interval of several fs to 500 fs. Some numerical results are typically shown for two cases of condensation behavior; 1) reaching to ground state oscillations as for D(H)2+ ion molecule, dμd muonic molecule, 3D+ ionic molecule, 6D/OSC and others, and 2) making fast collapse to get in the strong/weak nuclear interaction range of d-d (or p-p) inter-nuclear distance as for 4D(H)/TSC, 6D(H)/Rhombic-dodecahedron, 8D(H)/Rhombic-dodecahedron and 20D(H)/Rhombic-triacontahedron. Keywords: PC code, D(H)-cluster dynamics, ground state oscillation, fast collapse, 4D(H)/TSC, 6D(H)-Rhombic-dodecahedron, larger clusters, nuclear interaction, simulation of cold fusion
