Detailed Description

Initialises fields with default and zone values.

Original source file setFields.C

The default and zone values are read from a dictionary which defaults to system/setFieldsDict, cellZones are used to specify the internal field values and faceZone patch field values.

Usage

Any number of fields can be initialised on any number of zones, for example the 1D shock tube is initialised by

    defaultValues
    {
        U       (0 0 0);
        T       348.432;
        p       100000;
    }

    zones
    {
        lowPressure
        {
            type        box;
            zoneType    cell;

            box         (0 -1 -1) (5 1 1);

            values
            {
                T       278.746;
                p       10000;
            }
        }
    }

and the water in the tank of the rotatingCube VoF case is initialised by

    defaultValues
    {
        alpha.water 0;
    }

    zones
    {
        cells
        {
            type        box;
            zoneType    cell;

            box (-1e300 -1e300 -1e300) (1e300 0 1e300);

            values
            {
                alpha.water 1;
            }
        }

        patchFaces
        {
            type        box;
            zoneType    face;

            box (-1e300 -1e300 -1e300) (1e300 0 1e300);

            values
            {
                alpha.water 1;
            }
        }
    }

which sets both the internal and inlet values of the patch phase-fraction field.
