Class
    Foam::functionObjects::fieldCoordinateSystemTransform
 
Group
    grpFieldFunctionObjects
 
Description
    Transforms a user-specified selection of fields from global Cartesian
    coordinates to a local user-specified coordinate system.
 
    Operands:
    \table
      Operand      | Type                          | Location
      input        | {vol,surface}<Type>Field(s)   | <time>/inputFields
      output file  | -                             | -
      output field | {vol,surface}<Type>Field(s)   | <time>/outputFields
    \endtable
 
    where \c Type can be one of:
        \c Scalar, \c Vector, \c SphericalTensor, \c SymmTensor, or \c Tensor.
 
Usage
    Minimal example by using \c system/controlDict.functions:
    \verbatim
    fieldCoordinateSystemTransformFO
    {
        // Mandatory entries
        type            fieldCoordinateSystemTransform;
        libs            (fieldFunctionObjects);
        fields          (<wordList>);  // ( U UMean UPrime2Mean );
        coordinateSystem
        {
            origin      (0.001 0 0);
            rotation
            {
                type    axes;
                e1      (1 0.15 0);
                e3      (0 0 -1);
            }
        }
 
        // Inherited entries
        ...
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property  | Description                              | Type | Reqd | Deflt
      type      | Type name: fieldCoordinateSystemTransform | word |  yes  | -
      libs      | Library name: fieldFunctionObjects | word |  yes  | -
      fields    | Names of the operand fields               | wordList | yes | -
      coordinateSystem | Local coordinate system            | dict  | yes | -
 
    The inherited entries are elaborated in:
      - \link functionObject.H \endlink
      - \link coordinateSystem.H \endlink
