Hi Daniel,
I've used splash several times to convert SPH data to a 3D gridded file.
However, for some reason splash crashes (segmentation fault) with the
current data set if I use npix > ~120 (but below that threshold everything
runs fine. I tried with several number of particles etc. but the problem
persists).
Specifically, the crash seems to occur when `interpolate3D' is called (see
full output below).
Do you know where the problem could be?
Thanks for your help,
Max
PS: I am running version v2.7.0 [3rd May 2017]
