/RFILE/n
Engine Keyword Rewrites a Restart R-File.
Format
/RFILE/n
Ncycle
Definitions
Field | Content | SI Unit Example |
---|---|---|
n | (Optional) Number of restart files to be written before overwriting of the restart files begins. | |
Ncycle | Cycle frequency to write
R-file. (Integer, maximum 10 digits) Default = 1e6 Maximum value = 2.1e9 |
Comments
- If n is not defined then only 1 set of restart files is created and overwritten every Ncycle cycles. The name of the restart files is ROOT_i_CPU.rst where, ROOT is the rootname of the run, i is engine run number and CPU is MPI domain number.
- If n is defined then n sets of restart files are written before they are cyclically overwritten. To see which restart file was created last, review the Engine output file.
- The name of written restart is
ROOT_i_CPU_I.rst,
ROOT_i_CPU_J.rst.
Where, i is the Run number.
Example: if n=3, the first restart written is ROOT_i_CPU_I.rst, the second is ROOT_i_CPU_J.rst, the third is ROOT_i_CPU_K.rst, then ROOT_i_CPU_I.rst is overwritten.
- Consequently, with /RFILE/n, it is necessary to use: the /RUN option /RUN/Run Name/Restart Letter.
- Only Binary IEEE 64-bit format is used for the R-file.
