Foil 14 What is relation of NAS benchmarks to Navier Stokes Equations -- Space and Time Variables

From Introduction to Physics and Numerics of NAS Benchmarks CPSP713 Case studies in Computational Science -- Spring Semester 1996. by Geoffrey C. Fox


Note computational domain is the unit cube in x h and z space
We use these greek labels to indicate one has (notionally) transformed from original physical domain x h and z. (As noted the transformation matrix has been ignored)
We use t not t for two reasons
  • Firstly we probably have transformed time as well as space in map to computational domain
  • Secondly we only want steady state solution U and so we can view t as labelling iteration and not necessarily as time in a diffusive equation. This implies all that counts is accuracy at infinite time t and not accuracy at intermediate finite time t.
