2 What s New in ncode DesignLife 2018 Jon Aldred VP Product Management

3 ncode Latest release of DesignLife, released Jan 31, is part of ncode Moved from version numbers to a year based naming.

4 Timeline ncode

5 New for ncode DesignLife 13 & 13.1 Vibration fatigue compatible solvers Spot weld analysis Strain life (EN) analysis FEReader glyph Allows users to output all data available from supported FE files. FE results file format support Altair H3D support FEMZIP N (OptiStruct/Nastran OP2) Premium Materials Database 7 new material entries added to the database bringing the total number of material entries to 126. All materials tested at the Advanced Materials Characterization & Test Facility (AMCT) operated by HBM Prenscia in Rotherham, UK HBM 5

6 ncode DesignLife 13.1: Translation Speed Improvements 6 There is a significant increase of the processing speed when DesignLife is translating FE results. The speed up achieved depends on the: FE input file type Proportion of the FE results being used Analysis type. 10 times faster! 2.2 times faster! 27 Gb Spot weld ODB file 15 Gb FRF RST file 2017 HBM

7 ncode DesignLife 13.1: Loads reconstruction glyph 7 This new glyph uses virtual strains created by unit loads along with measured strain histories from gauges matching the virtual gauges to reconstruct the force histories required to cause the measured strains. Improved worked example (#20) Part of the Virtual Load Generation option 2017 HBM

8 ncode DesignLife HBM

9 New WholeLife Glyph for Welds in DesignLife 11 A new Unified Theory of fatigue developed with Prof. G. Glinka, University of Waterloo, Canada

10 New WholeLife Glyph for Welds in DesignLife 12 More accurate modelling of the complete failure process that leads to better correlation with test Uses standard seam weld modelling Ability to analyse the detailed design of individual welds Multiple failure modes may be investigated Efficient, only critical locations are analysed Supports multiaxial time based loading Residual stresses in weld may be included

11 WholeLife Analysis from Measured Data 13 It is also provided as a WholeLife glyph in the Fatigue palette

12 ncode DesignLife 2018: Translation Speed Improvements 14 There is a significant increase of the processing speed when DesignLife is translating FE results. Uses Processing Thread licenses above 2 simultaneous processes Saves time in the translation phase of the DesignLife analysis

13 ncode DesignLife 2018: Translation Speed Improvements 15 Using 2 processes, this example was over 30% faster 8 processes is 4.6x quicker

14 ncode DesignLife 2018: Virtual Sensor 16 Virtual Sensor feature in DesignLife Base Test / CAE correlation made easy Enables Modal Assurance Criterion Applications: General purpose Test-CAE correlation. Modal Assurance Criterion when comparing FE-based vs. test-based mode shapes.

15 ncode DesignLife 2018: Other Improvements 17 Vibration Fatigue: Vibration Analysis of Solid Seam Welds. Vibration Analysis of Seam Welds from Force Results. Walker mean stress correction method added to Standard SN Engine. Support for user selected critical plane angle. Editing of multiple material maps using the Edit Material Mapping now possible. PercentByEvent, TSToFETable, ModalCoordInput and ReSumLife are regular glyphs (no python). Removed need for X server libraries on Linux for HPC applications.
