advection term discretization

N.R.

Hi,

I would like to use a 2nd order central difference scheme for discretization of the advective term. (laminar flow, steady state). Any clues, why this doesn't work?

(Even something like including this in the CCL

ADVECTION SCHEME:

Option = Central Difference

END

will not work)

Numerical stability is not a problem. Accuracy is very important... What could I use as a substitute, if CFX doesn't offer that feature?

Thanks in advance,

N.R.
