Hallo, I have some problems to restart my runs. I tried to do it like it's described in the "NEK5000 Primer" (to change the line in the .rea file). Here my new entry in the .rea file: 1 PRESOLVE/RESTART OPTIONS ***** channel_old.fld01 But it doesn't work. Here the last lines of the log-file: set initial conditions Checking restart options: channel_old.fld01 TIME=130.78383346949016 Reading checkpoint data 0 0 OPEN: channel_old.fld01 640 6 6 6 1.3078383E+0210000 X Y Z U P NELT,NX,NY,N 0.000 0.000 0.000 0.000 0.000 NONSTD HDR, parse_hdr, abort. call exitt: dying ... backtrace(): obtained 12 stack frames. ./nek5000 [0x4de05a] ./nek5000 [0x5da15d] ./nek5000 [0x46e248] ./nek5000 [0x46ceff] ./nek5000 [0x46d302] ./nek5000 [0x471df0] ./nek5000 [0x47577b] ./nek5000 [0x407db2] ./nek5000 [0x4074ca] ./nek5000 [0x60c9ac] /lib/libc.so.6(__libc_start_main+0xe6) [0x7ff0e9c101a6] ./nek5000 [0x4073e9] total elapsed time : 1.09375E+00 sec total solver time incl.

I think you try to do a restart from an ASCII file using the BINARY reader! Is the restart file in ASCII or BINARY? Please post the header of channel_old.fld01 (e.g "head channel_old.fld01 | strings"). Stefan On Jan 21, 2010, at 6:01 PM, [email protected] wrote:

Uuups, sorry the header was printed in the logfile already. I think my first hunch was right - just change the read format in the .rea file to ASCII (see wiki) and you're all set. Stefan On Jan 21, 2010, at 6:19 PM, [email protected] wrote:
