Calumet MI, USA — This new version provides a major upgrade to the Graphics Window, support for Phase Change Materials, and many more powerful features to accelerate your CAE analysis and improve your simulation workflow.

New features significantly improve solution speeds and the user experience in Graphics Window Upgrade, Enhanced Fluid Streams, Phase Change Materials, Thermal Reports, Post Processing Enhancements, Battery Model Enhancements, Solar Lamp Enhancements, View Factors and CAE Coupling.

Following are more details about key new features:

1) Graphics Window Upgrade: A new Graphics Rendering Engine is now available. The graphics performance has increased by 10x-100x for most graphics window renderings. The new graphics requires OpenGL 3.0 or higher, and maximizes performance with high end graphics cards.

The legacy graphics system is still available to support older systems. The optimal graphics system will be automatically detected when starting the application.

Improved smooth shading algorithm accuracy with gradient contours. Enhanced the unique colors feature with more color options.

2) Enhanced Fluid Streams: Fluid Streams have major enhancements in this release. A new fluid stream algorithm improves the centering and quality of fluid stream generation. The fluid stream algorithm will generate paths through complex geometry, and provides the option to cancel the fluid stream generation if the path generation fails.

The new algorithm also improves the calculation of hydraulic diameter and heat transfer coefficients in fluid streams. Fluid streams setup has been simplified and inlets and outlets can now be specified with XYZ locations.

All fluid stream parameters are now included in the Summary Table and can be included in Boundary Condition sets. Fluid streams can now be selected graphically in the Editor or Post-Processor. Fluid streams are also now graphically rendered with temperatures in the post-processor and included in the auto-scale calculation.PCM graph

3) Phase Change Materials: Phase Change materials are now available and can be used to simulate solid-liquid phase change. The phase change solver has been optimized for the multi-grid solver for faster solution times.

The phase change feature can simulate encapsulated phase change materials and freezing/melting fluid materials where convective flows can be simplified.

4) Thermal Reports: Generated Thermal Reports are now automatically saved as a formatted HTML5 webpage for viewing all of the images, animations, plots, and results exports.

A new GUI has been created to setup thermal reports which includes a structured and graphical preview. Thermal Reports support adding headings and text to provide additional documentation of models.

Report templates can also use variables for frequently used title information, including the Date/Time, Model Name, and Application version. Thermal Reports will also monitor for any edits and remind the user to save prior to exiting.

5) Post Processing Enhancements: Post processing has several major enhancements, including the new Zoom to Max mode, which will automatically zoom and center the view to the maximum temperature based on the selected parts or elements.

Auto Scale button no longer pads the min/max display limits. New options to support large model post-processing have been added, including the new dynamic update feature which lets the user control if transient results are automatically loaded when changing time steps.

A new feature to directly enter time or time step values in the fields post-processor is now available. A new MergeFile tool can be used to join the results of multiple files which have been created using transient restart or transient initialization.

MergeFile will detect which time steps are available and create a single file with all of the results for post-processing.

6) Battery Model Enhancements: NREL Equivalent Circuit, NTG Equivalent Circuit, and NTG Distributed Battery Models now support having independent heat rates during charge and discharge cycles.

This allows for improved correlation during complex drive cycles with step changes in electrical loads. Single coefficients for charge and discharge are still supported.

7) Solar Lamp Enhancements: Solar lamps have been enhanced with intensity curves to simulate cases where the intensity changes as a function of time. Solar Lamp factors can now be adjusted to trade-off run-time versus accuracy.

A Solar Lamp Accuracy Wizard can be used prior to running a model to calculate the recommended setting. The solar lamp solver is faster, particularly for cases with a large number of solar lamps.

8) View Factors: Distributed Parallel View Factors now support the Intel MPI library as an option for MPI calculation. Use of the advanced radiation Mean Radiant Temperature feature does not calculate view factors for faces that enable this option.

9) CAE Coupling: Ensight export is now integrated into the main application and supports writing ASCII or binary Ensight case files.

Altair H3D files are now supported for reading or writing data to Hypermesh, RADIOSS, Optistruct, or other Altair programs. Options to support only geometry or with temperature results are available.
