Is it possible to get a copy of the interpolation code, to see how it is done? Then we can also check the interpolation scheme properties re: incompressibility.
Hi Paola,
if EVELMASS and NVELMASS are obtained by using
https://github.com/gaelforget/gcmfaces/blob/master/gcmfaces_IO/process2UEVN.m
then they're at tracer points.
