Hi neks,
I'm having some problems with the restart feature in the version 803 of
Nek5000. When I want to restart from a field-file, I get a warning
saying "WARNING: reading depreacted header!" and my program crashes
because of a division by zero. The file I use for my restart is from the
same version of Nek5000 and the header looks like
"#std 4 8 8 8 29016 29016 0.2500539468005E+02
2554 0 1 UPT "
followed by bytes. Nek5000 has been compiled with Intel compilers
(version 12.1.3) and OpenMPI (version 1.5.3). Is there something I'm
missing?
Best regards
Alex
