[Nek5000-users] define objects

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

dear neks,

is there an easy way to define objects? is there a possibility to do 
similar to the boundary conditions "set entire level"...? or do i have 
to add all faces by hand??
because i wanted to define my sphere as an "surface object" instead of 
using wall boundary conditions. cause i wanted to use the 'calc_drag' 
routine. and how i understood, this routines calculates the drag of 
objects, or??

best, fred
