Hi
I want to add a random horizontal walk to my floats, much like the vertical random walk already included. In step_floats.F on lines 213 and 214 there is reference to 'ifakt' and 'ifdak' - I can see that these are defined in mod_scalars.F - and they are indices into 'track'. What I can't find anywhere in the code is where 'track' is filled with a value at these index locations? The values I expect would be related to the vertical diffusivity in my *.in file?
Any help much appreciated.
Thanks
Evan
