problem with RESTART

[alexzive]

Hello,

I have to restart a truncated job (cause: interrupted power supply). In my original inp file I put

*Restart, write, frequency=50, overlay

Now I have the .res file. Note that original inp file is not in the abaqus-working-dir where the .res and all other simul. outputs are.

I restart typing

abaqus job=restart2 oldjob=E01_RVE_140px_mm_IS

my restart.inp file looks like this:
*HEADING
*RESTART, READ, STEP=1, INC=XX

Because it has been truncated at STEP=1 INC=24, I supposed XX=24. I also tryed all values before 24.
I always get the same error:

***ERROR: There is no restart frame on the old job at step 1, increment 24

it seems in the.res file there is no frame saved as supposed to be. How to look for saved frames into the .res file? (I cannot open .res file)
any help????

thanks, Alex

NOTE: this is a large job in ABQ-STD, requiring almost 9Gb memory.

*Restart, write, frequency=50, overlay

You asked for restart info every 50th increment - the analysis only got to 24 increments according to the status file.

Check *RESTART in the keyword manual.

which version of ABAQUS you using, there is a bug in the ABAQUS version 6.7.1 which they do not write restart file if the analysis did not finish.
you need the Version 6.7.2 onwards.

 

[bassmanjax]

Yeah but, if he asked for a restart write every 50 increments and only got to 24, then there won't be any restart (.res) file anyway....

Actually, I'll correct myself here. There probably is a restart file, only it'll be empty as the 50th increment was never reached.

Dear all,
thank you for your replay.

My ABQ version is 6.6-4

Actually my .res file is 9Mb big..
I misunderstood the meaning of frequency, thinking it refers to the time in sec of a step and not to the increments. So I was thinking it takes any total time (in my case 1*10^-3 s) and divide it by f(in my case 50) and save at the increment which is closest in time to this number.
I've checked the ABQ-Documentation and for sure I am wrong and bassmanjax is right.

From now on I will adjust f in order to save every few inc with overlay because it takes sometime many h of comput. time for each inc.
Bye, Alex
