Using grid spacing calculator for laminar flow

CH

hello,

i would like to check if it's possible the use the grid spacing calculator at the nasa site to estimate the grid spacing for laminar flow e.g. at Re=1000 or Re=10000.

e.g. if Re=1000, the spacing is given as 0.01 unit (at y+ = 1). does that mean the 1st line of grid must be 0.01 unit away from the wall?

thank you
