Re: [Nek5000-users] Using postx








Hi Rich,

This example is on [0,2pi]^2.  Because it is a verification study 
for which we wish to test convergence, the geometry is rescaled in 
the .usr file (see routine usrdat) to get full 64-bit precision.

If you go to:

http://nek5000.mcs.anl.gov/index.php/UG#Documentation

and click on Examples, you'll get a .pdf that describes
the problem (p.6).

Paul
