[Nek5000-users] Re post-processing using f0000 files

Hi,

Thanks so much for your reply.

The visit file obtained after running the usr file attached last email is
called pipe0.f00001. Visualization of pipe0.f00001 shows the peak value of
streamwise velocity is 0.0003 which should be around 1.3 in non-dimension.
So I guess the averaging process is wrong in usr file. Would you please
have a look at the averaging calculation in usr file is correct.

The 2D mesh was generated firstly using pretex and extruded to 3D via
n2to3.

If the averaging process is correct, may I know how I can use Paraview or
VisIt to get the line data. By the way, is there any way to get profile
like channel flow as shown below,

      if (nid.eq.0 .and. istep.gt.0 .and.
     &   mod(istep,iostep_avg).eq.0) then
         write(6,*) 'Dumping statistics ....'
         open(unit=56,file='reystresses.dat')
         write(56,'(A,1pe14.7)') '#time = ', time
         write(56,'(A)')
     &   '#  y     y+     R_uu     R_vv     R_ww     R_uv'
         open(unit=57,file='means.dat')
         write(57,'(A,1pe14.7)') '#time = ', time
         write(57,'(A)')
     &   '#  y     y+    Umean'


Kind regards,

ZJ
