6.2.4. Run Sequence and OVERFLOW Mode Control

The "RunControl" section of pyOver.json contains settings that control how many iterations to run OVERFLOW, what mode to use for each subset of iterations, and command-line inputs to the various OVERFLOW binaries. The entire contents of this section, with all default options applied where necessary, is written to a file called case.json in the folder created for each case.

Several subsections of this section are described separately.

The options for this section have the following JSON syntax.

"RunControl": {
    // Phase description
    "PhaseSequence": [0, 1],
    "PhaseIters": [200, 400],
    // Job type
    "MPI": false,
    "qsub": true,
    "Resubmit": false,
    "Continue": true,
    "nProc": 8,
    // Environment variable settings
    "Environ": { },
    // System-wide resource settings
    "ulimit": {
        "s": 4194304
    },
    // Solver command-line inputs
    "overrun": {
        "cmd": "overrunmpi",
        "aux": "-v pcachem -- dplace -s1"
    },
    // Archive settings
    "Archive": { }
}

Some of these options are common to all solvers, and the full description of such settings can be found on the corresponding Cape page.
