numerical schemes

is it possible to solve flow equations with different numerical schemes (with fluent)?

in other words can i solve momentum equation along x-axis with a numerical schemee and along y-axis with another numerical scheme???

(can i be able to do this with UDF???)

Hi

Why do you want to do that?!!!

It's usefull for me do this because i've studying a flow field with a velocity component very low respect two other (two order of magnitude). The lower velocity component is so affected by numerical diffusion.... i've thought to use only for this velocity component a low diffusion numerical scheme or central difference scheme.
