A fully automated Chimera methodology for multiple moving body problems

A fixed-grid model for simulation of a moving body in free surface flows

“…To reduce computational costs of the remeshing process required by the global mesh system, the overlapped mesh system, which is also called multi-block mesh system or Chimera grid system, has been proposed [3,18,38]. In this approach, unstructured grids that conform to the body surface and follow the body motion are only arranged in the vicinity of the moving body and the rest of domain is discretized by fixed structured grids.…”

Parallel domain connectivity algorithm for unsteady flow computations using overlapping and adaptive grids

“…Other notable domain connectivity packages include SUGGAR/DiRTlib [15], CHIMPS [16], BEGGAR [17], and FASTRAN [18]. These packages (including those mentioned in the paragraphs above) all have their merits and drawbacks.…”

Unstructured grid immersed boundary method for numerical simulation of fluid structure interaction

“…Unfortunately, it is very inefficient or even impossible to simulate large amplitude motions, for which a remeshing procedure (Garcia and Onate, 2003;Pellertier et al, 1994) is needed to deal with low mesh quality. Chemira grids method (Wang and Parthasarathy, 2000;Chen and Liu, 2002) is another choice for large amplitude moving body problems. Some researchers adopted an immersed boundary method to simulate fluid flow and rigid body interaction on a fixed mesh in the last couple of years.…”
