deal.II is a C++ library supporting the generation of complex adaptive finite element codes. It features locally-refined grids, various scalar and vector-valued finite elements, linear solvers of low and higher order, arbitrary mappings, and support for 1, 2, and 3D computations. It comes with extensive documentation and example programs showing the use of the library for modern finite element programs.
Engauge Digitizer is digitizing software that converts an image showing a graph or map into numbers. The image file can come from a scanner, digital camera, or screenshot. The numbers can be read on the screen, and written or copied to a spreadsheet. Highlights for beginners include an intuitive interface and extensive context-sensitive documentation. Highlights for experts include compensation for image distortion, cartesian and polar coordinates, linear and logarithmic coordinates, automatic scanning, graphical previews, and browser help.
