Qucs 0.0.4 has been released.

Qucs 0.0.4 has been released.

The Qucs project (Qucs = Qt universal circuit simulator) today
announced the immediate availability of Qucs 0.0.4, a Qt-based
advanced and powerful microwave circuit simulator for GNU/Linux and
other UNIXes.

Qucs, including all its libraries and its applications, is available
for free under Open Source licenses. Qucs can be obtained in source
code from <http://sourceforge.net/projects/qucs>.


Qucs provides a GUI based on Qt for setting up microwave circuits, a
simulator, which is able to simulate the small- and large signal
behaviour of microwave circuits. The results can be shown on a
special presentation page in different formats (rect, polar, smith,

Compiling Qucs 0.0.4

The complete source code for Qucs 0.0.4 may be freely
downloaded. Instructions on compiling and installing Qucs 0.0.4 are
included in the software archive. Only Qt-Libs >= 3.1 and the glibc
are essential.

About Qucs

Qucs is an independent project of only a few developers, translators,
etc, collaborating over the Internet to create and freely distribute a
sophisticated, customizable and stable microwave circuit simulator.
For enhancing the development speed we are looking for more
developers, who want to support the Qucs Project.

Changes in this release

The new release includes a per-language internal help system. It
comes with translations into Portuguese and Spanish. Some new
paintings and components have been added, subcircuits can have a
user-defined symbol. Also zooming has been improved and a progress
bar during simulation is available.

The simulation backend implements ideal AC, DC and S-parameter models
for microstrip t-junctions and cross-junctions. Support of transient
analysis for linear and non-linear components has been added as well
as the AC simulation for all available components. Current and
voltage pulse sources (single and rectangular) are now available.


Lot of thanks go to the translators and to the supportive user
responses so far encouraging us to improve the software. We couldn't
have done it without you!
