Working with finite elements you will use the structures FE2d and FE3d. As these classes are derived from Triang2d and Triang3d all methods which are available for the Triang classes can be used. New are some display methods. The method "isoline-disp" allows you to display level lines of your finite element structure. "superlevel" allows you to display an area with values greater then the given level. There exists an interpolation method that allows you to interpolate between two FExd objects (including the FE data). In case you need local refinement you will need the class Adapt2d. After specifying the triangles which should be refined a new triangulation is produced using this data. A subclass of Adapt2d is Geom2d which is mainly used for visualizing surfaces. If allows to store additional information like normals, colors, parameter lines and boundary curves.
