SimMechanics Release Notes

Known Software and Documentation Problems

This section includes a link to a description of known software and documentation problems in Version 1.1.

Platform Limitations

SimMechanics has some platform limitations.

Virtual XWindows Servers

Virtual XWindows servers, such as Xoftware, are not supported in the MATLAB environment and do not function well with SimMechanics and other MATLAB Java-based applications.

Virtual Reality Toolbox Viewers

• The default viewer functions on UNIX/Linux platforms.
• The blaxxun Contact plugin viewer is not supported on UNIX/Linux platforms.

Changing Block Properties

You should not change SimMechanics block properties at the command line.

Configurable Subsystems Not Supported

Simulink configurable subsystems do not function if the configurable subsystem library has SimMechanics blocks.

Currently Unsupported Simulink Features and Tools

Certain Simulink features and tools are currently not functioning with SimMechanics blocks or SimMechanics models.

Currently Incompatible Toolboxes and Blocksets

SimMechanics is currently incompatible with Nonlinear Control Design Blockset.

Virtual Reality Visualization

The presentations of virtual reality visualization in the SimMechanics User's Guide assume that you are using the blaxxun Contact 4.4 plugin viewer for Web browsers. Consult the Virtual Reality Toolbox User's Guide for instructions on using the new default viewer.

Rendering and Animation Bugs

These are sporadic minor problems with virtual reality visualization:

• If the machine is not initially visible in the browser, try closing the browser and restarting, or try the browser's Refresh or Reload buttons.
• When you update a diagram, the virtual reality scene might not update as it should. Click the browser's Refresh or Reload buttons to update the scene manually.

Internet Explorer Bugs

Microsoft Internet Explorer sometimes malfunctions while viewing a virtual scene through the blaxxun plugin viewer.

• You sometimes see a nonfatal console error dialog while viewing a virtual scene. Click on OK in this dialog if you see this error.
• Microsoft Internet Explorer 6 sometimes fails if you use it as the default browser for virtual reality. Restart the visualization from the Mechanical Environment Settings dialog if this happens.
