Local Inverse Mapping Implicit Hole-Cutting Method for Structured Cartesian Overset Grid Assembly [PDF]
Entropy, 2023 An automatic hole-cutting method is proposed to search donor cells between a structured Cartesian mesh and an overlapping body-fitted mesh. The main flow is simulated on the structured Cartesian mesh and the viscous flow near the solid boundary is ...

Performance of Overset Mesh in Modeling the Wake of Sharp-Edge Bodies
Computation, 2020 The wake dynamics of sharp-edge rigid panels is examined using Overset Grid Assembly (OGA) utilized in OpenFOAM, an open-source platform. The OGA method is an efficient solution technique based on overlap of a single or multiple moving grids on a ...

Overset Grid Assembler and Flow Solver with Adaptive Spatial Load Balancing [PDF]
Applied Sciences, 2021 In the present study, a parallel unsteady and coupled flow solver is developed to solve fluid flow around relatively moving components using a system of multiple unstructured meshes overlapping each other in a parallel computing environment. The use of multiple overlapping meshes is also referred as overset mesh methodology, which is convenient in ...

Developing Spline Based Overset Grid Assembling Approach and Application to Unsteady Flow Around a Moving Body [PDF]
Journal of Mathematics and System Science, 2016 Overset or Chimera grid approach is one of methods to cope with complex geometries. A spline based overset grid assembling system has been developed. The sys- tem is based on structured grid approach and covers comprehensive features for overset assembling, i.e., grid generation, grid modification, and computing Receptor-Donor Con- nectivity (RDC) for ...
