NAME

       iofem - input and output finite element manipulators

DESCRIPTION

       This   class  implements  some  specific  finite  element  manipulators.   For  a  general
       presentation of stream manipulators, reports to class iostream.

VALUATED MANIPULATORS

       origin

       normal set a cutting plane for visualizations and post-processing.

              cout << cut << origin(point(0.5, 0.5, 0.5)) << normal(point(1,1,0) << uh;

       topography
              specifies  the  topography  field  when  representing  a  bidimensionnal  field  in
              tridimensionnal elevation.

              cout << topography(zh) << uh;

              This  manipulator  takes  an agument that specifies a scalar field value zh for the
              elevation, while uh is the scalar field to represent. Then, the  z-elevation  takes
              zh(x,y)+uh(x,y).
