WebMesh convergence is an important consideration in both Abaqus/Standard and Abaqus/Explicit. The connecting lug will be used as an example of a mesh refinement study by further analyzing the connecting lug in Abaqus/Standard using four different mesh densities ( Figure 1 ). The number of elements used in each mesh is indicated in the figure. WebSep 1, 2024 · The CFD simulation conditions in this study are listed in Table 3. The wave heading in the range of 0°–135° was selected for analysis and comparison, so the selected forward speed and wave height are relatively gentle. Table 2. Definition of wave headings. Table 3. CFD simulation conditions.
