Class
    Foam::functionObjects::fieldCoordinateSystemTransform
 
Group
    grpFieldFunctionObjects
 
Description
    Transforms a user-specified selection of fields from global Cartesian
    coordinates to a local coordinate system.
    The fields are run-time modifiable.
 
Usage
    Example of function object specification:
    \verbatim
    fieldCoordinateSystemTransform1
    {
        type    fieldCoordinateSystemTransform;
        libs    ("libfieldFunctionObjects.so");
        ...
        fields  ( U UMean UPrime2Mean );
 
        coordinateSystem
        {
            origin      (0.001 0 0);
            rotation
            {
                type    axes;
                e1      (1 0.15 0);
                e3      (0 0 -1);
            }
        }
    }
    \endverbatim
 
    Where the entries comprise:
    \table
        Property     | Description                          | Required | Default value
        type         | type name: fieldCoordinateSystemTransform | yes |
        fields       | list of fields to be transformed     | yes |
        coordinateSystem | local coordinate system          | yes    |
    \endtable
