What's new in 20-sim 4.1.2.2:

March 1st, 2010

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:
· 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.
· 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.
