[Nek5000-users] Nek compiles on IBM, but not on Intel

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

Sorry for the inconvenience, we try hard not to break user space. The interpolation wrapper has been refactored and is no longer compiled by default.

Add the following two pre-processor commands to the top of your .usr file
#include "intp.f"
#define INTP_MAXPTS 10000

Then, just call intp_setup(), intp_do(), intp_free(). Please note, that the API has changed.

Same for g2gi() - grid to grid interpolation - which was replaced by our new generic fld reader gfldr()

Cheers,
Stefan
