24 Application
25  postChannel
26 
27 Description
28  Post-processes data from channel flow calculations
29 
30  For each time: calculate: txx, txy,tyy, txy,
31  eps, prod, vorticity, enstrophy and helicity. Assuming that the mesh
32  is periodic in the x and z directions, collapse Umeanx, Umeany, txx,
33  txy and tyy to a line and print them as standard output.
34
