[Nek5000-users] turbChannel: Definition of CFL and write/print files

[nek5000-users at lists.mcs.anl.gov]

Hi Emily,

You can write out field data at specific points within your domain by using
the history points feature. Simply set up a file *casename*.his in the
format specified in the user guide. Then in usrchk() in the .usr file
include
call hpts
This will write the field data at the specified points at every timestep.
Make sure that the max hpts parameter in your SIZE file is greater than the
number of points you have specified in your .his file. The data will be
written into the .his file as well.
