cordin_info.h5

This file contains 1-D arrays of the grid coordinates in the following format: 

cordin_info.h5:
- /xc(r)
- /xm(r)
- /ym(r)
- /zm(r)
xc contains the wall-normal coordinates of the grid cell faces and is of length nxm+1. xm, ym, and zm are the coordinates of the grid cell centres, and are arrays of length nxm, nym, and nzm. The post-processing module afidtools reads this file by calling the class afid.Grid(fld).

means.h5

means.h5:
- /vybar
  -- /0000
  -- /0001
  -- ...
- /vxrms
- /epsilon
- /chi
Profiles as a function of \(x\) and time, output at the regular interval defined by t_out in bou.in. The helper function read_mean() is provided in the afidtools module to read this data.

The files in flowmov contain 2D slices of the state variables (\(\boldsymbol{u}\), \(T\), \(S\), \(\phi\)). The three plane slices produced are at \(x\approx 0\) (taken at the first grid point from the wall), \(y=L_y/2\) and \(z=L_z/2\). The slices are output at the regular time interval defined by t_frame in bou.in.

fields

Each file in fields contains one 3D array from a single time snapshot, under the group name /var.
