[Nek5000-users] Outpost question

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

Hi Katherine,

Thanks for the answer. I knew about the parameter 15 and was not sure about
the 64 bits precision. This is now more clear.
Regarding the overwriting, I had guessed that prepost has a parameter that
needs to be reset, but I haven't been able to figure out which one so far.
That would be very helpful if you can take a quick look at it.

Thanks a lot and enjoy the end of the summer
