>From the lines of your logfile, I see the first filename G1_640.f00005 read correctly
Reading checkpoint data
0 1 OPEN: G1_640.f00005
while the next filename you are trying to read shows up as
0 1 OPEN: .fld
which means the second file Nek is trying to read is ".fld" for some reason -- I would suggest checking how you set the filename for the second file.

I am sorry, I don't understand your reply:
my rea file tells me that p66 and p67 specify binary or ascii. We use always binary.
How does the particular name file enter?
