[Nek5000-users] Degrees of freedom

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

Josh,

4081752 is the number of pressure degrees of freedom

the other is the number of velocity degrees of freedom
(save that you need to multiply by 3, since there are
3 velocity components at each gridpoint).  So, in effect,
the first number is the rank of the Helmholtz operator for
each of the 3 velocity components.
