rectangular mesh cell reduce only one dimension?
 

Hello all

I have a very simple geometry, the automatic generated mesh are rectangular cells. Say they are 5x2 rectangular (just to present length ratios of the sides of rectangulars), how can I reduce the "5" side and make the cells 2x2 or even the other way around 2x5? This because I want to put more cells along the flow direction I care more.

Thanks a lot.
