Hi Volker,
Many thanks. In fact, this was my intention, thanks for noticing my
mistake. Re-running the code I noticed that I made another mistake
compiling the code with *EXTRA_HIGH_EWALD_ACCURACY,* *PMGRID*, and *FMM*. I
understood that for the PM-FMM gravity solver Ewald corrections were not
needed and was expecting the sims with and without *EXTRA_HIGH_EWALD_ACCURACY
*to be the same at machine precision. This is not the case, have I
misunderstood something? Many thanks for the help.
Regards,
