[Nek5000-users] Dump on both regular and SEM grids

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

   Hi Aleks,

   Does Nek automatically creates this equally spaced regular grid or 
should we create it ?

   At present I am using 'Hpts()' to dump data, but it is lot of time 
and memory consuming

   I can create a regular mesh using a small routine but how do I make 
NEK to dump data to that particular mesh ?

   What is  ' nrg '  ?

   Thanks,
   KS
