Free simulation and modeling software for mac

Wave Simulation 1.0 is developed as a smart program which is simulative to a wave disturbance propagating on a two dimensional membrane. The program uses a timer to step the simulation. At each step a two dimensional wave equation is solved by using a finite differencing scheme that is space centered and time forward. The initial conditions have been exaggerated for better visibility in the OpenGL output. See the commentary in the source code for further details. The idea here is to demonstrate simple numerical processing and scientific visualization in a Cocoa based application.

The program structure uses the Model/View/Controller paradigm. The classes for this structure are grouped under one heading and the various support classes are grouped under another heading. The View part of the program combines the user interface (UI) and the OpenGL rendering. The GLView class is a wrapper, i.e., sub-class, around the NSOpenGLView class that gives the class the ability to render, among other things, a mesh that is passed in from an outside source.

The view point and lighting that the GLView class uses in its rendering is also provided from outside. The visible part of the GLView in the UI is an outlet for the rendering. Also, the GLView object has been set up so that a mouse click in the visible rendering area toggle betwever, each update cycle is quick enough to justify a single threaded structure for the program.

An important characteristic of this program is that the OpenGL rendering is encapsulated in two parts of the program: the GLView class and the DrawingFunctions.h module. All of the other support classes make no reference to OpenGL. The Avian class is meant to capture the concept of an extended physical body that can have a location in 3D space as well as an orientation.

The FlyingCamera class is based on the Avian class and provides it with extras that are appropriate for handling views from various positions and orientations. The Mesh and MeshNode clases are also divorced from OpenGL. A GLView object 'knows' what to do with FlyingCamera and Mesh objects, but not vice versa. Also, the Controller object 'knows' how to relate user input, via the steppers, to FlyingCamera settings.

This program is also provides a good way to waste enormous quantities of time. The membrane uses a material that is meant to be a fair approximation of ruby. When the light is set to, say, colatitude equal to 35 degrees and longitude equal to 200 degrees the surface shows some nice highlights. Be warned: this program can induce a hypnotic state in the unwary user.

Qucs (Quite Universal Circuit Simulator) 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.
Qucs is a circuit simulator with graphical user interface (GUI). The GUI is based on Qt by Trolltech. The software aims to support all kinds of circuit simulation types, e.g. DC, AC, S-parameter, Harmonic Balance analysis, noise analysis, etc.
Qucsator, the simulation backend, is a command line circuit simulator. It takes a network list in a certain format as input and outputs a Qucs dataset. It has been programmed for usage in the Qucs project but may also be used by other applications.
Qucs is currently developed under the GNU/Linux OS using the standard autotools with no special effort to support other operating systems.Qucs can also be successfully compiled and run on Mac OS X, Solaris, NetBSD, FreeBSD, Windows and Cygwin.

Enhancements
- The new release comes with new translations into Arabic and Czech, model libraries for PMOSFETs, NMOSFETs, regulators, varistors and ideal components, and many new primitive components such as EPFL-EKV NMOS/PMOS V2.6, rectangular waveguide, HICUM L0 v1.2, HICUM L2 v3.23, photodiode, digital buffer, microstrip radial stub, phototransistor, RLCG transmission line and numerous new digital primitives.
- Passing parameters to Verilog-HDL and VHDL subcircuits and typed generic parameters of VHDL files are now supported as well as arbitrary in/out signals.
- Simulation time for digital files (Verilog and VHDL) are now stored in an additional configuration file and the import dialog has been replaced by a complete import/export frontend for the Qucs-Converter command line tool. US letter formats for schematic frame have been added. The build system now implements an additional install step for MacOSX and the appropriate icons.
- In the analogue simulation core global nodes (e.g. subst!) have been introduced, property references inside the same instance of a component and variables in constant parameter simulation boxes are allowed.
- A noise figure property has been added to the amplifier model and the matrix power operation is available in the equation solver.
- The Qucs-Converter command line tool allows now to translate existing HICUM models into library elements as well as the translation of polynomial Cs and Ls and F, H, E and G polynomial SPICE sources.
