The readFields function object reads fields from the time directories and adds them to the mesh database for further post-processing.


Operand Type Location
input vol<Type>Field $FOAM_CASE/<time>/<inpField>
output file - -
output field vol<Type>Field Mesh database

where <Type>=Scalar/Vector/SphericalTensor/SymmTensor/Tensor.


Example of the readFields function object by using functions sub-dictionary in system/controlDict file:

    // Mandatory entries (unmodifiable)
    type            readFields;
    libs            (fieldFunctionObjects);

    // Mandatory entries (runtime modifiable)
    fields      (<field1> <field2> ... <fieldN>);

    // Optional entries (runtime modifiable)
    readOnStart true;

    // Optional (inherited) entries
    region          region0;
    enabled         true;
    log             true;
    timeStart       0;
    timeEnd         1000;
    executeControl  timeStep;
    executeInterval 1;
    writeControl    timeStep;
    writeInterval   1;

where the entries mean:

Property Description Type Required Default
type Type name: readFields word yes -
libs Library name: fieldFunctionObjects word yes -
fields Names of the operand fields wordList yes -
readOnStart Flag to start reading on start-up bool no true

The inherited entries are elaborated in:

Usage by the postProcess utility is not available.
