Dear all
I am trying to use nek5000 to simulate Rayleigh Benard convection in a
vertical cylinder with heated bottom cooled top and insulated sidewall.
All the wall boundaries are set no slip.
The hight to radius ratio is 1.0.
The Prandtl number is 0.02 and Ra=4000.
 The .rea and .usr file are changed from ray_dd.rea and ray.usr in
$HOME/nek5_svn/examples/benard/.
 The files are attached.

My problem is with these files I can't get right result.
Could any one help  to find out where the problem is?

Regards,
Bofuwang
