General

New Features

Stackmath
The Add Stackmath Operation supports multiple arguments for individual parameters. Use the entity editor to change the parameter options.

New Readers

Exodus
The Exodus reader in HyperGraph allows you to plot results for .frq and .ex2 files generated from the Exodus solver.
HBM Test Files
Support for HBM temperature measurement test data files. The supported file extension is .tem.
Animator .a4db
Support for .a4db files with curve data from the Animator database. HyperGraph supports LS-DYNA and Abaqus solver-based .a4db files.
Seam
Seam reader in HyperGraph allows you to plot seam results in the form of .out files. This reader is available with an environment variable (HW_ENABLE_SEAMREADER = 1).

Enhancements

  • Plot Browser enhancements:
    • Symbol attributes added to the Plot Browser's entity editor, visible when a curve is selected from the Plot Browser.
    • X and Y curve vector units are supported through the Plot Browser's entity editor. A units block for X and Y vectors to change curve units from the Plot Browser using the entity editor.
    • Label Prefix and Label Suffix are updated with new options MaxY and At X. Select these options in the entity editor to display the maximum Y value of the curve with the X coordinate in the legend as a label.
    • Curve prefix and suffix shortcuts in a Templex expression from the Plot Browser's entity editor. For example, a note attached to a curve can access suffix and prefix information using a Templex expression such as {p1w1c1.suffix} and {p1w1c1.suffix}.
  • Macro panels support multiple arguments for parameters.
  • Value-based curves can be exported as an RPC file, along with previously supported file-based curves.
  • Previously, if a CSV file with blank spaces was imported into HyperGraph, the reader ignored the data after the blank space. To address this, from the Plot Browser's entity editor, select Invalid Point Mode > Bridge or Gap option. Bridge handles the blank spaces by creating a bridge in the plotted curve and Gap handles the blank spaces by displaying a gap in the plotted curve.
  • HyperGraph supports RPC3 files created by a floating point format and a short integer format, reading results properly.
  • Filter added to Channel Mapping in the Flexible Report Templates dialog. Filter data types and requests with a string. Wild card support is not available.

Resolved Issues

  • Tic increment value of zero causes HyperGraph to close unexpectedly.
  • readsim function issue when sorting element IDs.
  • Requests not populating in the Build Plots dialog after loading the file into the HyperView Build Plots panel.
  • Copy/paste issue with 3D curves.
  • In the Build Plots dialog, added a filter for X vector requests.
  • Issue related to curve offset using TPL with flexible report template.
  • Acceleration time history can be plotted in HyperGraph using results from an Abaqus ODB file. The acceleration time history can then be exported as a DAC file and then imported into nCode for further data processing. When exporting the curve data to the DAC file from HyperGraph, the units were not exported properly, which caused errors during data processing.

Altair HyperGraph 2020 Release Notes

General

New Features

Extreme Curves
The Extreme Curves dialog allows you to filter maximum contributors or minimum contributors based on a design aspect from set of curves.
Curve Correlation
The Curve Correlation dialog returns correlation metrics in the form of notes using correlation algorithms. These functions will be used to calculate correlation metrics between test and CAE data. Sprague-Geers Combined Metric (SGCM) and Weighted Integrated Factor (WIFac) are supported in this release.
Add Stackmath Operation
The Add Stackmath Operation dialog allows you to create a math stack on a curve. After applying a math operation on a curve, the curve is redrawn per the math without creating duplicate curves. The dialog's entity editor displays the math function's parameters, which you can change as necessary. Only a limited number of math functions are supported in this release.
Advanced Build Plots Enhancements
From the Create Curves by File dialog > Multiple Inputs tab, use Ignore strings in requests to ignore strings in requests while plotting multiple files. This functionality is useful when comparing the same results with different prefix ID’s.
Lock Axes
The Lock Axes option replaces the Auto Fit and Fit Range options on the Axes panel and in the Plot Browser. Options for Lock Axes include Never, Always, and At Import.

Enhancements

Shock Response Spectrum (SRS)
The Shock Response Spectrum (SRS), a standard mathematical function that is commonly used in space systems with acceleration time history as the base input, is now included as a standard math function in HyperGraph.
Bubble Help for Order Numbers
Waterfall 3D plot curves display bubble help to identify order numbers in the NVH Order Analysis utility.
