[Nek5000-users] Interpolating data from unifom grid to a GLL grid

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

Hi Navin,

In general, transfer from a uniform grid cannot be done 
in a stable manner with polynomial interpolation.
One could, however, use splines or piecewise quadratic.
We don't have a routine set up to do this but you could
probably mimic the GLL to Uniform routine.
