Hi Emily,<div><br></div><div>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</div><div>call hpts</div><div>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.</div><div><br><div class="gmail_quote"><div dir="ltr">On Wed, Feb 14, 2018, 3:02 PM <<a href="mailto:nek5000-users@lists.mcs.anl.gov">nek5000-users@lists.mcs.anl.gov</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<p class="MsoNormal">I have a couple quick and preliminary questions. Could you please tell me where could I find the definition of CFL; more specifically, the file/subroutine where CFL is related to the time step, etc. The other question is that which file
shall I go to add/modify lines to write out some field information in a file (like .dat files or so) or print on sreen?<u></u><u></u></p>
