[Nek5000-users] Extracting data and interpolating

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

Hi Neks,

I am currently working on simulation of 3D curved pipe with Nek5000. I
would like to export some data in mid-slice surface and specified line
along the curvature of pipe. I am using USERCHK, I can export the
variables, but how I can interpolate/write data which desired along the
lines and sliced surfaces? and If I do this kind of interpolation,
interpolation can keep the accuracy of the simulation or not?

Thanks,
Ami
