[Nek5000-users] SFD error message from p66

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

Hello

I implemented an SFD for a 2d cylinder

https://bitbucket.org/cpraveen/nek5000/src/master/ext_cyl/

It seems to work but the residuals reduce by about 5 orders of magnitude
only. Maybe I am not choosing the parameters correctly. I would like to see
how others do it and compare with my own implementation.

Best
praveen
