Default Smallest mesh size

Hello,

I'm trying to mesh a 2D airfoil in Gambit, I need an extremely fine mesh near the boundary - I will use this mesh in a DNS calculation.

I have problems using a grid space of 1e-07 in GAMBIT, the mesh is in meters.

Any idea why I have such a limitation and how may I avoid this ?

BTW in GRIDGEN it seems to be no problem with a 1e-07 meters division.

Thanks.

Hi

Gambit works in mm, not in meters. And you have to use boundary layer in place of directly putting a grid if you want fine grid. But I doubt grid size of 10e-7 to be sufficiently fine for DNS
