The equations shown in the last section can be resolved and equivalent results can be calculated by Rocky considering the same input data and boundary conditions. The input parameters for this verification case setup are presented in Table 2.1: Verification case input parameters. and the geometry dimensions are shown in Figure 2.2: Flat surface geometry dimensions..
