omitting restart files (*.rst) as output

Altair Forum User

Hi,

 

I run IMPDYN analysis from Optistruct and get two .rst files per run. I understand that these .rst files are from RADIOSS. Is there a way to avoid these rst files in Optistruct if I do not want them as output? They take my harddisk space too much...

 

Best regards,

Tanut

Hi,

You can use Control File, using /TIME & /CYCLE/cycle_number  .

• This will stop the job a cycle = “cycle_number ”  without writing a .rst file
  

 

 

 

 

Control File (C-File)

 

 

The C-file is an optional Control File.

File format is Runname_run#.ctl, where run# is the current job number (four digits) from 0001 to 9999.

It can be used to:

•get information on a running job;

•stop the computation at a given time or at a given cycle number;

•write an A-file, U-file, or E-file at a given time or cycle number.

If a plot file is asked for, this file will have the number of the last written file plus “1”.  If the computation is not stopped, the normal writing frequency of plot file is not changed.

If a time (option /TIME) or a cycle number (option /CYCLE) is omitted, the requested action is taken when control file is read by RADIOSS.

Besides /INFO, the following keywords could be combined with any others:

/INFO

/TIME/time value

/CYCLE/cycle number

/STOP

/KILL

/ANIM

/RFILE

/CHKPT

 

INFO returns information on current cycle, current global energies, current time step. It could not return information in given time (defined in /TIME/time value) or in given cycle (defined in /CYCLE/cycle number).

STOP writes a restart file R-file and stops the job

KILL stops the job without writing an R-file

ANIM writes an A-file

RFILE writes an R-file

CHKPT writes “CHECK_DATA” file

The action taken and the information are returned in the C-file itself.

 

Comments

1./CHKPT should not be used with implicit computation.
