Release highlights

The release of nCode 2024.0 brings improvements in functionality and performance for nCode DesignLife, nCode GlyphWorks, and nCode VibeSys software products encompassing 155 built-in processing and display glyphs and support for over 50 data formats. 

Current customers on active software maintenance can gain access to nCode 2024.0 and full release documentation using the Support Portal.

GlyphWorks 01

Decode Vector ASC raw CAN data with the CAN processing Glyph

The CAN processing glyph can now decode raw CAN data from Vector ASC files. As with the other supported file formats, in combination with a CAN database (.dbc) the raw CAN data is decoded into channels of data in engineering units which can then be processed downstream.
The user can select which channels to be decoded from a list of available channels in order to speed up the extraction. The decoding can be performed in a user-supplied time range, and a time offset can be applied, so the decoded data can be synchronised with additional data from other sources. nCode 2024.0 supports decoding raw CAN data contained in ASAM MDF4 files and HBK catman BIN files as well as the newly supported Vector ASC files.

Improvements to Optimised Testing

The TestMatch glyph has been improved with the addition of three new properties. The new properties (CorrelationLimit, YTolerance and XTolerance) allow user control over the convergence of the solution.

GlyphWorks 02
GlyphWorks 03

Automatic Re-submission of Batch Jobs – Beta Feature

Batch jobs can now be automatically re-submitted after a failure due to license availability. The new functionality is supported in both flowproc and the DesignLife specific dtproc. This feature is controlled by the use of two new command line switches that control the number of re-tries and the time period between the re-tries.


Other enhancements:

  • Support for Python 3.11 has been added to the currently supported 3.8.
  • Matlab 2023b is now supported in the Matlab scripting glyph.
  • The Matlab 7.3 file format is supported for output.
  • ASAM ODS ATF/ATFX (ODS versions up to 6.1 are now supported).
     

Release highlights

CAN Processing

Decode CAN data with new CAN Processing Glyph

The CAN Processing glyph can be used in conjunction with a CAN database (.dbc file) to decode raw CAN data into channels of data in engineering units, which can then be further processed downstream.
The user can select which channels to be decoded from a list of available channels in order to speed up the extraction. The decoding can be performed in a user-supplied time range, and a time offset can be applied, so the decoded data can be synchronised with additional data from other sources. nCode 2023.1 supports decoding raw CAN data contained in ASAM MDF4 files and HBK catman BIN files.
 

Synchronize data using time offsets in the TestCombination glyph

The TestCombination glyph can now apply time offsets to Time Series and Multi-column input tests. This enables the user to easily synchronize data coming from various sources. This is particularly useful when tests involve multiple data collection devices such as video cameras, CAN loggers, mobile DAQ systems, etc. and the engineer needs to process the entire data for a global understanding of the physical phenomena occurring.

File format enhancements:

  • Multi-column nCodeDS CSV file now supported as output format.
  • ASAM ATFx file format can be read directly without using the ASAM browser.
  • Siemens LMS .LDSF files can be read in conjunction with an associated ATFx file.
  • Other file format updates for ASAM MDF4, Dewesoft DXD, and Dewetron DMD.
     
Improved formatting capabilities for tables

Improved Formatting Capabilities for Tables

GlyphWorks is a great tool for crunching data and reducing it to useful metrics that usually end up in a multicolumn table. Tables can be sorted and filtered but the Multi Column Manipulation glyph has been improved with two additional methods to format result tables: 

  • Summary Table is particularly useful when manipulating data from multiple tests 
  • Transpose for rows to become columns and columns to become rows.

Coloured Features on Time Series

The XY Display glyph can now set and display individual colours for each feature type from a feature list. This is particularly useful when looking at measured data where different sections highlight different phenomena. 

 

There may be multiple section types, each defined with a particular user-defined condition. In this case each section type can be displayed with a specific colour;

Usability improvements

Usability Improvements

nCode 2023 introduces a number of usability improvements. This includes enhancements to existing glyphs such as the Concatenation glyph, which can now have more than two time series input pads, making a workflow with multiple input files to be concatenated easier to build and more readable.

 

Other improvements include the information of a flow file version in the Journal when the flow is loaded in nCode.

Multi-temperature Dang Van Analysis

The capabilities of the Dang Van safety factor analysis have been extended to include the effect of high temperatures for powertrain.

 

A new material type has been introduced to allow the use of multiple Dang Van curves at different temperatures.

 

This is an iso-thermal analysis where a single temperature is obtained for each entity in the FE model.

Multi-temperature Dang Van
Adhesive bond improvements

Adhesive Bond Improvements

A new modeling method using solid elements to assess the durability of adhesive is introduced. This is in addition to the current method using beam elements.

 

This new modeling method also enables the use of the standard SN solver. This method is possible due to the more ductile nature if newer adhesives.

The free edges of the solid elements can be wrapped in a skin of membrane elements and the new X_Stress or Y_Stress option can be used for the analysis.

Further enhancements

Additional improvements in nCode 2023 include:

  • Overall spectrum available as a specific option in the ComplexFrequencyManipulation glyph  
  • MATLAB MAT file format supported up to version 7.3 
  • Time series can be saved in the MDF 4 file format 
  • CSV files now readable directly as Time Series
  • New vibration fatigue glyphs available for EN, spot weld and seam weld analyses
  • New worked example for vibration loading with modal coordinates 
  • Seven new materials in the premium material database 
  • Three new FKM material databases (5th, 6th and 7th editions of the FKM Guide

Electric power insights

In the nCode 2022 release, the Electric Power glyph has been improved and now offers a new method for calculating electric power results, referred to as the Instantaneous method. This method offers a much more accurate estimate of the AC reactive and apparent power. It calculates the AC, DC and mechanical power and efficiencies from electric and mechanical digitized data. It also allows one to observe how power evolves at a much higher time resolution. With this more accurate method, Electrification engineers can further optimize the electric powertrain in order to increase the vehicle range.

Both the Electric Power and Surface Plot glyphs provide advanced post-acquisition signal processing and power calculations that is ideal for use with Power Analyzers such as HBK's eDrive.

Displays and reporting

nCode 2022 introduces a new optional ‘peak X cursors’ in the XY Display glyph. When selected, X cursors are automatically positioned using a ‘peak valley’ algorithm to find significant peaks in the data. Customers can now define the number of peaks to consider.

This new option applies to Time series, 2D histograms or frequency spectra and can be saved as default configuration, so that any new data displayed in an XYDisplay glyph or in the viewer will have its peaks highlighted.

Local PSD outputs for Virtual Sensor

The latest addition to the Virtual Sensor is the ability to be used on a FE model driven by vibration loads. In this case, the FE-based displacements from a frequency response function (FRF) analysis, either direct or modal, can be used to extract local Power Spectral Densities (PSD) at specific locations. The outputs PSDs can be in terms of displacement, velocity, or acceleration. These "virtual accelerometer" outputs are particularly useful for defining vibration tests of sub-components from the FE model. The FE results can be either direct or modal-based frequency response function (FRF).

Improved model validation with the hot spot glyph

In nCode 2022 there is a new hotspot option to include adjacent locations along with each of the identified hot spots. This option works for both element and nodes and allows the user to easily examine the variation in the results around each critical location and therefore helps to determine the validity of the stress results in those locations. This option is also available in the elimination post processor.

Further enhancements

Additional improvements in nCode 2022 include:
  • Time series file formats updates: Dewesoft DXD, Vector MDF4, HBK BKC
  • The MDF4 file support is now included with Prenscia Access
  • Matlab 2021b is now supported in the Matlab scripting glyph
  • Save Process With Data option also saves a .flo file
  • Brown-Miller added to the multi-axial EN solver options
  • Updated support for all the major FE codes
  • Additional materials in the standard database
  • Constant and variable amplitude seam weld data
  • Two new aluminium seam weld materials
  • New ASME steel seam weld
  • PamCrash FEMZipped files now supported
  • Four versions of Abaqus ODB will be supported at this release: 2017, 2018, 2020, 2021

Vehicle electrification

In support of our many customers’ focus on the electrification of vehicles and other forms of transportation, nCode 2021 includes specific capabilities to aid the post-processing of huge amounts of measured electric motor test data. A new Surface Plot glyph is ideal for torque vs speed efficiency and loss mapping for AC motor tests. The Surface Plot also has many other applications for general XYZ mapped data. Support for the reading of large .PNRF files recorded at high sample rates by HBK's eDrive Power Analyzer has also been improved in this release.

Vibration Profile Design

Vibration Profile Design enables engineers to construct or accelerate a profile for shaker tests based on real world data, saving both time and money in environmental qualification and product validation. In this release, capabilities are expanded to enable the Shock Response Spectra glyph to calculate fatigue damage spectra based on acceleration, velocity or displacement responses to cater for different failure modes. Additional time series outputs for user-specified frequency points are also provided in order to better understand the dynamic response. Vibration Profile Design is an invaluable analytical addition to electrodynamic shakers such as HBK’s LDS shaker systems.

Further enhancements

Additional improvements in nCode 2021 include:

  • Simulation of weld fatigue is enhanced with improved automatic seam weld detection to handle more complex geometries. Walker mean stress correction is also added for seam weld analysis.
  • FE Results files supported are updated including MSC Nastran 2020 .h5 and ANSYS 2020 R1 .rst. Abaqus ODB file versions 2017, 2018, 2019 and 2020 are all supported at this release.
  • FE Display is now faster to switch displayed groups for models with large numbers of properties or materials.
  • Video Player glyph is now fully multi-threaded for faster import of multiple simultaneous videos and optionally stores translated files for immediate re-loading.
  • Customer-driven enhancements including updates to supported file formats such as binary UFF, Dewesoft .dxd and Vector MDF4.

Some features listed were also included in nCode 2020.1.
