Implications of Shallow Water in Numerical Simulations of a Surface Effect Ship
Overset, or Chimera, meshes are used to discretize the governing equations within a computational domain using multiple meshes that overlap in an arbitrary manner. The overset meshing technique is most applicable to problems dealing with multiple or moving bodies. Deep water simulations were …

Multi-rate time integration on overset meshes
… or multiscale spatio-temporal features, overset meshes can be effectively used. However, in the case of overset problems in which one or more of the meshes vary significantly in resolution, standard explicit time integrators limit the maximum allowable timestep across the entire …

Improved Design Method for Cambered Stepped Hulls with High Deadrise
… series of validation studies utilizing fixed and overset meshes led to a final simulation set up with an overset mesh that allowed for accurate prediction of drag, trim moment, wetted keel length, and the wake profile aft of the cambered planing surface. The database is fitted such that the final …

Propeller Noise Prediction of an Urban Air Mobility Vehicle in Urban Environment
… This section explores the application of the Overset mesh method for propeller simulations in OpenFOAM and compares its performance against the Arbitrary Mesh Interface (AMI) approach in OpenFOAM. While AMI has been extensively validated for rotor acoustics, it is limited in handling large …
