Class
    Foam::functionObjects::syncObjects
 
Group
    grpUtilitiesFunctionObjects
 
Description
    Copies content of local objectRegistry to all processors.
 
    Currently only supports IOFields. It is used to distribute IOFields
    from different processors/regions/worlds
    when doing loose coupling. To be used in combination with 'mapped'
    boundary conditions.
 
Usage
    Example of function object specification:
    \verbatim
    syncObjects1
    {
        type        syncObjects;
        libs        ("libutilityFunctionObjects.so");
        ...
 
        // Where is data located relative to runTime. Given as a filename
        // with every '/' indicating a sub-objectRegistry w.r.t. runTime.
        // Local data is under <root>/send/processorXXX. After execution
        // (potentially remote) data will be under the corresponding
        // <root>/receive/processorYYY objectRegistry.
        //root        "level0/level1/level2";
    }
    \endverbatim
 
    Where the entries comprise:
    \table
        Property     | Description             | Required     | Default value
        type         | type name: syncObjects  | yes          |
        root         | relative location of data  | no          | ""
    \endtable
