Abstract:

Simple upwind schemes are the basis of many codes of practical importance for design studies in heat transfer and fluid flow applications, e.g. the FLOW3D code. With care, it is possible to produce codes that can give bounded answers regardless of mesh spacing or time step size. This note highlights a rather disturbing inaccuracy that can arise if the mesh spacing is taken too large. Keywords Mathematical models Errors Great britain.
