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.
xcircuit is software for drawing electrical circuits.
What is Z88?
Z88 is a fast, powerful and compact Finite Elements Analysis Program
especially designed for PCs, workstations and large computers with UNIX
and PCs with Windows XP/95.
FEATURES
# Z88 features 20 finite element types.
# It covers plane stress, plate bending, axial symmetric
structures and spacial structures up to 20-node Serendipity hexahedrons.
# Comes with a user-friendly interface (the Z88 Commander).
# Has a powerful mesh generator.
# Features a DXF converter and two plot programs.
# Contains the FEA solver featuring an in-situ Cholesky solver along
with the Jennings storage method.
# For large structures the new iteration solver is recommended.
# The import of COSMOS and NASTRAN files from Pro/ENGINEER (with
option Pro/MECHANICA) is possible.
Open CASCADE Technology is a software development platform freely available in
open source. It includes components for 3D surface and solid modeling,
visualization, data exchange and rapid application development.
Open CASCADE Technology can be best applied in development of numerical
simulation software including CAD/CAM/CAE, AEC and GIS, as well as PDM
applications.
BUGS: the interesting parts of this port are the libraries, but some components
like Wok are not [yet] fully functional.
TkGate is a event driven digital circuit simulator with a tcl/tk-based
graphical editor. TkGate supports a wide range of primitive circuit elements as
well as user-defined modules for hierarchical design.
The distribution comes with a number of tutorial and example circuits.
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
FreeWnn 是一个日文、中文、韩文输入法。
这个 port 仅含有一个中文输入法的类库。这个类库包含了客户端所需要的一个归档文件
(libcwnn.a),头文件和其它一些文件。
注意,如果你使用 Wnn 的客户端,则必须设置环境变量 CSERVER 或 TSERVER。
