The roll motions are influenced by significant viscous effects such as the flow separation. The 3D
simulations of free decay roll motions for the ship model DTMB 5512 are carried out by Reynold averaged Navier-
Stokes (RANS) method based on the dynamic mesh technique. A new moving mesh technique is adopted and
discussed in details for the present simulations. The purpose of the research is to obtain accurate numerical prediction
for roll motions with their respective numerical/modeling errors and uncertainties. Errors and uncertainties
are estimated by performing the modern verification and validation (V&V) procedures. Simulation results for
the free-floating surface combatant are used to calculate the linear, nonlinear damping coefficients and resonant
frequencies including a wide range of forward speed. The present work can provide a useful reference to calculate
roll damping by computational fluid dynamics (CFD) method and simulate a general ship motions in waves.
