PyCAM is a toolpath generator for 3-axis CNC machining. It loads
3D models in STL format or 2D contour models from DXF or SVG files.
The resulting GCode can be used with EMC2 or any other machine
controller.
PyCAM supports a wide range of toolpath strategies for 3D models
and 2D contour models.
PythonCAD is a CAD package written, surprisingly enough, in Python. The
PythonCAD project aims to produce a scriptable, open-source, easy to use CAD
package for Linux, the various flavors of BSD Unix, commercial Unix, and
other platforms to which someone who is interested ports the program. Work
began on PythonCAD in July, 2002, and the first public release was on
December 21, 2002.The firs developer team stop to develop PythonCad In the
2007.In May 2009 A new developer team star to develop Pythoncad since now.
Qfsm is a graphical editor for finite state machines written in C++ using Qt.
Finite state machines are a model to describe complex objects or systems in
terms of the states they may be in. In practice they can used to create
regular expressions, scanners or other program code.
Current features of Qfsm are:
- Creation, editing, loading and saving of binary and ASCII machines
- Drawing of states and transitions
- Binary and ASCII condition codes
- Setting of a start state and end states
- Zooming
- Cut, copy & paste inside Qfsm
- Printing of diagrams
- Multiple windows
- Integrity check
- Interactive simulation
- AHDL/VHDL export
- State table export (Latex, HTML)
Qucs is an integrated circuit simulator which means you are able to
setup a circuit with a graphical user interface (GUI) and simulate the
large-signal, small-signal and noise behaviour of the circuit. After
that simulation has finished you can view the simulation results on a
presentation page or window.
TOCHNOG is a free finite element program with many features. TOCHNOG
accepts free format input. Boundary conditions can be imposed at
geometrical entities, as well as nodes and elements.
Among the FE models supported are: differential equations (materials),
convection-diffusion equations, Stokes and Navier-Stokes (fluids),
elasticity (isotropy and transverse isotropy), plasticity (Von-Mises,
Mohr-Coulomb, etc.; plastic surfaces can be arbitrarily
combined). Residues in equations and error estimates for all data can
be printed or plotted using gnuplot/plotmtv, CalculiX or gmsh.
TOCHNOG supports a choice of description frames including Lagrangian,
Eulerian and arbitrary Eulerian-Lagrangian (AEL).
VARKON can be used as a traditional CAD-system with drafting, modelling
and visualization if you want to but the real power of VARKON is in
parametric modelling and CAD applications development. VARKON includes
interactive parametric modelling in 2D or 3D but also the unique MBS
programming language integrated in the graphical environment.
The system was originally developed by a group at the University of
Linkoping in Sweden during 1984-86 under the leadership of Dr. Johan
Kjellander who was then the president of Microform AB. From 1986 the
system was owned, marketed and further developed by Microform AB.
Transcalc is an analysis and synthesis tool for calculating the electrical and
physical properties of different kinds of RF and microwave transmission lines.
Transcalc was somewhat inspired by the functionality of Agilent Technologies'
commercial program linecalc. Transcalc aspires to be more functional in the
long run and well-documented with appropriate references to formulas that are
used. Transcalc is built using the GIMP toolkit (GTK) for its GUI interface.
For each type of transmission line, using dialog boxes, you can enter values
for the various parameters, and either calculate its electrical properties
(analyze), or use the given electrical requirements to synthesize physical
parameters of the required transmission line.
Available transmission lines (this list will expand with subsequent releases):
- Microstrip
- Rectangular Waveguide
- Coaxial Line
- Coupled Microstrip
