Default Curvilinear boundaries

Hello, I write my Fortran-program for the 3D incompressible Navier-Stokes equations on the multiprocessor computer (cluster). Different ways of dealing with curvilinear boundaries are known: 1) the generalized curvilinear coordinateses; 2) non-uniform cartesian grids; 3) multiblock uniform cartesian grids which take more finer near boundary. What way is better? What grids (structured or unstructured) it is better to prefer? Thank.

Lew.

hi that depends on your application, also time available , your understanding of the variety of methods ! Obviously the unstructured grid methods are most flexible in handling geometries but the coding in 3-d is most complex. Don't go for orthogonal grids which refine near boundaries.Non-orthogonal curvilinear grids (multi block)are the best compromise but u have to see whether your geometry is mappable or not.Still this is the best possible approach for most of the people.
