[Nek5000-users] subroutines of gradm1 and interp_v3

Hi Jian,

gradm1 is a routine in navier5.f that you should be able to use on any mesh to compute the gradient of any field.

interp_v is an interpolation routine based on fgslib_findpts. In v17, a wrapper has been made available to use these routines. See intp_usr.f in the repo for these wrappers, and the hemi example in the Nek example repo for its usage.
