1.      Resistance coefficients are based on wetted surface area (S/L²) = 0.1476 for static orientation in calm water.

2.   ITTC-57: C_F =0.075/(log₁₀Re-2)²

3.   C_R =C_T - C_F

4.      Comparison Error, E%D=(D-S)/D×100, where D is the EFD value, and S is the simulation value. E%ITTC is computed based on ITTC value.

5.      Relative change in solution: e₁₂%S₁ = |(S₁-S₂)/S₁|×100.

6.      Iterative uncertainty U_I is based on fine grid solution. The value is evaluated using change in solution in two consecutive time steps for converged solution.

7.      p_G,th is the theoretical order of accuracy = order of convection scheme.

8.      U_G is the grid uncertainty. U_SN = sqrt(U_I²+U_G²) is the simulation numerical uncertainty.

9.      U_D is the data uncertainty.

10.  U_V = sqrt(U_D²+U_SN²) is the validation uncertainty.

11. Brief details of the V&V equations should be provided in the paper.
