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.
