[Nek5000-users] Prandtl number in the heat transport equation

Hi Alexandre,

You can take a look at nek5_svn/ examples/benard/ray_cr.usr to see how 
buoyancy term can be setup.  There we set Pr=1 but you can define it as a 
combination of parameters from .rea file.

Let me khow if you have further questions,
Aleks
