Calculation of Flow Fields Using Overlapping Grids

  • Laszlo Fuchs
Part of the Notes on Numerical Fluid Mechanics (NNFM) book series (NNFM, volume 29)


A numerical scheme that is based upon a combination of Multi-Grid methods and systems of overlapping grids is presented. The main advantages of the the overlapping grid system are as follows: it allows easy generation of grids for complex geometries; it makes it possible to solve problems with variable geometries, and that all this is gained without the penalty of slow convergence. Some new features have been added recently to the scheme. One of these is the possibility to treat colliding objects. The flexibility of the method is demonstrated in calculating some steady and time dependent flows.
