20-Sim v4.1.0.5 Windows Server

20-sim is a modern modeling and simulation program that runs under Microsoft Windows.
With 20-sim you can simulate the behavior of dynamic systems, such as electrical, mechanical and hydraulic systems or any combination of these.
20-sim 4C is a prototyping environment that enables you to connect 20-sim models to physical systems. The models can be executed as real-time C-code on hardware like PC's or ARM-9 based processor boards. Excellent ARM-9 demonstrators are the TS-7300 Demonstration Kit and the Torsion Bar prototype machine.

What's new in 20-sim?
General Features
The Parameter Editor and Variables chooser show the model icons in the model tree.
Any model or plot can be exported to bitmap (png file).
You can enter library paths for library models, c-code generation, export to matlab and template files.
Editor
A brand-new Document Editor can be used to generate output files (html) for Word Processors and Presentation software.
A Find box has been added to the button bar.
Simulator
Simulation buttons have been added to Secondary plot windows.
Library
Signal:
The model derivative has been added.
The model second derivative has been added.
The square wave generator model has been changed. The internal frequencyevent has been relaxed from 1e-15 to 1e-14 to prevent the integration method from stopping when running stiff models.
Hydraulics:
A hydraulic inertia has been added.
The four three way directional valve models now have four spool centers (open, closed, tandem and floating).
The four three way proportional valve models now have four spool centers (open, closed, tandem and floating).
The pressure relief valve and pressure reducing valve models have updated icons.
A counter balance valve has been added.
A pilot operated check valve has been added.
New hydraulic example models have been added:
Cylinder Slip - 1.emx
Cylinder Slip - 2.emx
Cylinder Cavitation - 1.emx
Cylinder Cavitation - 2.emx
You can add your own libraries (Windows folders) to be displayed in the library browser.
New models have been added to the library.
The function linsolve now has optional methods (lu, qr, cholesky, gmres)
Various models have been combined into one model (having multiple implementations)
Frequency Domain Toolbox
In the Linear System Editor you can reduce the order of a system by pole zero cancelation.
In the FFT analysis you can indicate the peaks in an FFT plot.
3D Animation Toolbox
A brand-new Movie Creator will help you to create movies from 3D Animations with few mouse clicks.
The 3D Animation window is equipped with a toolbar.
3D Mechanics Toolbox
3D Mechanics models can be opened from the 20-sim Editor.
Acceleration Sensors have been added to the library.
You can add a spring and damping to a joint and define endstops.
Solved Bugs
Initial Equations with global variables are now correctly solved.
Ports of models that are generated with the 3D Mechanics Editor now have the right domain (now: translation or rotation, was: power).
In windows Vista, bitmaps are correctly shown in a 3D Animation.
Imploding and Exploding models that have an implementation now works fine.
Incorrect initialization of matrices in initial equations solved.
Showing peaks in FFT plots improved.
