Z88 is a fast, powerful, and compact finite elements analysis program. Z88 features 20 finite element types; it covers plane stress, plate bending, axial symmetric structures, and spacial structures up to 20-node Serendipity hexahedrons. It comes with a user-friendly interface (the Z88 Commander), and has a powerful mesh generator. It features a DXF coverter and two plot programs. The FEA solver is included, featuring an in-situ Cholesky solver along with the Jennings storage method. COSMOS and NASTRAN files from Pro/ENGINEER can be imported. Z88 is a project of the University of Bayreuth, Germany.
PDFSlide is an application for displaying PDF-based presentations, such as those created by Beamer. It includes a presenter mode with current and next views. The timer view shows the current time and the elapsed presentation time. Apple Remote support is also included, which allows the presentation to be remotely controlled.
Hormiga is a language designed to be simple and powerful, allowing users without software programming knowledge to make the programs needed to automate the calculations of everyday problems. Generally, it is necessary only for the users to be aware of the problem they want to solve. The language allows programmers to focus on the problem and not to worry about the interactive interface with the user. The programmer will have to state the instructions to solve a problem, in the same way they would do manually. The steps may depend one upon the other. Like most languages, Hormiga has support for functions and the possibility of creating libraries of commonly used code. Unlike most languages, Hormiga automatically and dynamically creates the graphical user interface (GUI) for programs, has support for calculating definite integrals in multiple dimensions, and incorporates a new concept called Step, similar to a procedure of Pascal, but allowing you to state dependences between them.
Brace is a dialect of C that looks like Python. It has coroutines, hygenic macros, header generation, and libraries with graphics and sound. It is meant to be good for beginners, kids, and experts. Brace is translated to C, then compiled, with #! support and cached executables. It is fairly portable, and runs on GNU/Linux, Unix, and Windows with MinGW. It should also run on Mac OS X. It comes with a lot of demo programs, many with animated graphics.
FidoCadJ is a very easy-to-use editor, with a library of electrical symbols and footprints (through hole and SMD). Drawings can be exported in several graphic formats (PDF, EPS, PGF for LaTeX, SVG, PNG, and JPEG). Although very simple and not relying on any netlist concept, FidoCadJ can be considered a basic electronic design automation program. FidoCadJ uses a file format containing only UTF-8 text, which is very compact and suited for copying and pasting with newsgroups and forum messages. This determined its success, as it is quite versatile for simple mechanical drawings as well as for electronics.
JHeatChart is a one class Java API for generating heat map charts that was created because very few charting APIs seem to contain the facility to create heat maps. It is not a full featured charting API and cannot be used to other charts. The generated charts are created as Java Image objects, which can be incorporated into a GUI or saved to a file.
