00047    In this file we define some constants to use as parameters to
00048    some fei functions.
00049    These constants are primarily used as 'fieldType' arguments to
00050    fei::VectorSpace::defineFields and FEI::initFields.
00051    If defining a vector-field for displacement, use DISPLACEMENT. If
00052    defining separate scalar fields for the components of displacement,
00053    then use DISPLACEMENT_X, etc.
00054    Most of the names below are self-explanatory. PRESSURE refers to either
00055    a vector-field for pressure, a nodal pressure variable, or the constant
00056    coefficient for a pressure field that is discontinuous in each element.
00057    PRESSURE_X, PRESSURE_Y, and PRESSURE_Z refer to the X, Y, and Z coefficients
00058    for a linearly varying pressure field defined separately in each element.
