Hi nek's
I'm trying to perform a DNS of a turbulent channel flow ussing the tutorial "turbChannel.f".
I have some troubles about the subroutine "planar_average_s", in particular when I generate a mesh using genbox in a single box, it works very well, such that the vector "yy" goes from -1 to 1.
On the contrary when i split the box in genbox in two boxes, "yy" goes from -0.5 to 0.5 and it is repeated two rimes (-0.5, ... 0.5, -0.5, ..., 0.5), of course the averages have no sense.
Could someone help me?
Thanks
