Hi, exports.

I am trying to solve a 3D finite wing using simpleFoam.

I made two grids. One is wall spacing is 1e-4, and the other is 1e-5.

And the same total mesh number, B.C, input.

But in 1e-4 case, the calculation is convergence.

but 1e-5 is divergenced. The time step continuity error is gone infinite.

In wall spacing is 1e-4, my yPlus is

min : 0.1417616, max : 59.2992, avg : 8.770113.

In my opinion, when I solved 2D airfoil. The same problem was occurrenced.

Does anyone have same issues?
