Dear Customers and Partners,

 

We are pleased to announce that SPEOS for PTC Creo 2014 SP2 is now available!

This new version includes new measurement capabilities and better report generation enhancing users’ productivity.

Color analysis and luminaire performance check have never been so easy to use.

Ergonomics of simulation settings and result analysis are improved thanks to local meshing and false color ray tracing.

 

We really hope you will enjoy this new version of SPEOS for PTC Creo.

 

If you have any questions, please contact your local Optis subsidiary.

Local meshing

 

 

Local meshing is introduced for complex systems requiring different levels of meshing definition:

 

  >>  Globally at the simulation level, for all the selected geometries

 

  >>  Locally at the part level, in the Optical Properties, for all the solid bodies and quilts

 

  >>  Locally at the surface level, in the Face Optical Properties, for the selected list of faces

 

In some cases when the geometries of interest needs a finer meshing definition compared to the rest, initialization of the simulation is faster.

 

Simulations can be faster without any impact on the quality of the results.

Colored rays

 

 

Visualization of the colors according to spectrum and wavelength during ray tracing has been extended to the source preview in the 3D as well as Light Expert ray tracing for the Creo Parametric integration.

 

 

 

Each ray takes the color corresponding to its wavelength, giving important visual information to the users.

Colored rays

 

 

Source properties permit to select one of the 5 different false colors so the user is able to distinguish the different sources of an interactive simulation, making analysis easier.

 

 

 

This property is available in both Creo Parametric and Pro/ENGINEER Wildfire integrations.

 

 

 

 

 

 

Light Expert – Next rays

 

 

User has the possibility to observe different rays when using the Light Expert ray tracing.

 

Next rays function permits to scan through the Light Path Finder file and get the following set of rays that hit the selected area of a simulation result.

 

User has a full overview of the different paths the light takes until reaching the sensor.

Source power for LED definition

 

 

The power of low power LEDs is often defined using a reference to their luminous intensity.

 

Surface source offers the possibility to set the on axis intensity instead of the flux.

 

 

 

 

 

 

For luminaire source, luminous flux or radiant flux can now be adapted to real flux corresponding to the real LED flux or power delivered by the ballast.

Enhanced analysis with measurements

 

 

Spectral maps give access to new types of magnitude to perform color measurements according to the colorimetric system.

 

 

For instance average, minimum, maximum color values over an area or along a line can directly be measured.

 

 

User can also easily observe color variations using the section panel.

 

 

Color and spectrum data as well as Color Rendering Index panels can be accessed using the line shapes.

 

 

 

 

 

Enhanced analysis with measurements

 

 

Some requirements specify the width of iso levels to describe the target distribution.

 

 

User has the possibility to measure those widths with the new range measure available for User line shape.

 

 

The range represents the width between the first point of the line and the point at which the threshold value is found, starting from the second point.

 

 

This point coordinates can also be displayed using Range_X and Range_Y measures.

 

 

 

 

 

 

 

Enhanced analysis with measurements

 

 

The new Point shape for measurement permits to easily get values along a section and compare them with another profile.

 

 

This measurement shape can be reviewed from the SPEOS tree and in the simulation report.

 

 

It can also be used to Optimization and Tolerance analysis targets.

Enhanced analysis with measurements

 

 

Global rules extend the analysis capabilities by defining constants or variables linked to measurements by formulas.

 

Global rule results can be:

 

  >>  Numerical and used for instance to compute the difference between two flux values.

 

  >>  Boolean to compare numerical expressions.

 

They can be part of the equation permitting to validate a Rule target.

 

Global rules can be reviewed from the SPEOS tree and in the simulation report:

 

  >>  In the Measures section when they are numerical,

 

  >>  In the Rules section when they are Boolean.

Miscellaneous

 

 

Ambient source visualization

 

User can rapidly identify the direction and orientation of the ambient source references:

  >>  Zenith in purple

  >>  North in brown

  >>  Sun in yellow

  >>  Moon in black

 

 

 

Warning management

 

Warnings can be deactivated from the main properties panel to avoid repetitive messages to appear during the use of SPEOS.

 

 

 

Miscellaneous

 

 

Temperature field preview

 

The visualization of the thermic source’s temperature field has been enhanced to easily size the geometry as well as orientate it.
