[Nek5000-users] Regarding Interpolation on to a Cylindrical Grid

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

Hi Paul, Alex and Nek's,

I want to interpolate the data from the Cartesian mesh on to a 
Cylindrical mesh that I created using python.

The Idea is to interpolate the data at each step and to perform post 
processing on it.

1) I tried to dump data using hpts(), but the problem is that the size 
of hpts.out gets larger after each time step.

2) Looking into g2gi subroutine, tells that both the *.rea have to be 
built via nek5000.

It would be really helpful for all the users, If some kind of example 
(stenosis or turbchannel) is added about the solver based data post 
processing with USERCHK(), (GLL --> Uniform grid) interpolation.

Best Regards,
KS
