Verification and Validation Study of OpenFOAM on the Generic Prismatic Planing Hull Form
… to fully planing regimes. Firstly, the mesh convergence study and Verification and Validation (V&V) study are performed on the basis of fixed attitude simulations. Three grids are chosen and used to perform the free attitude simulations at the highest speed. Then, mesh convergence study …

The effect of bend radius on the impulse transfer characteristics of V-hulls
… model, the optimum element length for the air mesh was obtained by performing a mesh convergence study on the Arbitrary Lagrangian-Eulerian (ALE) mesh, and validated using the impulse values measured from a 58 g detonation onto a 120° V-plate as it resulted in the highest impulse. Element …

Finite Element Study of Plane Wave Acoustic Phenomena in Ducts
… finite element factors such as shape functions, mesh refinement, and element distortion. The study concluded that the higher order shape function eight-node quadrilateral element gave considerably better results than lower order shape function four-node quadrilateral element. The eight-node …

Behavior of reinforced concrete column-beam joint subjected to close in blast loads with polyurea and FRP sheets
… of 400 MPa. Parametric analyses examined mesh-density sensitivity, explosive charge weight, blast-mitigation performance of various coatings like Poly urea and FRP Sheets. Numerical models were first validated against experimental contact-explosion tests on RC bridge columns (Yuan et al., …

Genetic Algorithm Based Optimization of Baffle Positions in a Forward Osmosis Draw Channel
… using similar simulation conditions. Mesh convergence and OpenFOAM flow-variable solver studies are then conducted to minimize solution inaccuracy and computation time. Finally, a genetic algorithm is implemented via the open source optimization toolkit DAKOTA which allows optimized …

Compression After Impact Experiments and Analysis on Honeycomb Core Sandwich Panels with Thin Facesheets
… each damage detail on overall analysis results. Mesh convergence of the new FEM is also discussed. Analysis results are compared to the experimental results for each of the 32 CAI sandwich panel specimens tested to failure. The failure of each specimen is accurately predicted in a high-fidelity, …

Application of Numerical Methods to Study Arrangement and Fracture of Lithium-Ion Microstructure
… error plays a significant role in establishing a mesh-convergent solution for uniform fragmentation problems. Further, by using differing magnitudes of randomized material properties and mesh discretizations, we find that employing randomness can improve convergence behavior and provide a …

Vibro-acoustics of porous materials with periodic inclusions
… especially in terms of computational times and mesh convergence. On the other hand, analytical models, although being partially limited by approximating assumption, constitute a powerful tool to quickly understand physics and general trends of the problem. Even if porous and poro-elastic media …

Finite-element simulations of interfacial flows with moving contact lines
… contact angle or the contact line velocity, and meshindependent results can be obtained following a simple computational strategy. We have implemented the method in three dimensions and provide numerical studies that compare well with analytical solutions to verify our algorithm. We first develop …

Extension and further validation of a 3D two-phase flow model for flow, transport and mass transfer in sewer systems
… which the setup was then investigated for grid convergence using different mesh resolutions. Mesh convergence was investigated using different tools and observing residuals for each parameter, providing a better understanding of flow behaviour versus simulation time required. The chosen mesh was …
