**Oasys 21.0 W1 (Workflows Update 1)** This section lists all the changes made to **Virtual Testing** Workflows since the Oasys 21.0 release. # **Automotive Assessments** ## **Enhancements** 1. All the Structure channels which take PARTs as input in the Far Side + VTC crash test now have a single entity selection textbox. This means you only have to select entity IDs once for such channels and eliminates the need to perform the same repetitive selection multiple times. 2. Graphs for failed occupant assessments (e.g. missing channel data) are now displayed with a helpful title explaining that there was no output for that particular assessment. 3. Structure assessments can now be plotted for imported data (e.g. ISO-MME or CSV). The structures are derived from ISO-MME channel data (by matching channel codes to Structure names). 4. When clicking EDIT for a entity textbox that contains a list of parts, the Edit window will appear for each part successively after clicking Yes on a window that asks if you want to keep editing (previously only the first part was shown). 5. Removed restriction of suppliers to just the supported list: ATD-MODELS, DYNAmore, Humanetics, LSTC, PDB. Users can now define their own custom supplier name. 6. Added a new Euro NCAP Virtual Far Side VC2 (Assessment Criteria) REPORTER template for Validation Criterion 2. 7. Added Head Excursion assessment type for Far Side + VTC crash test. 8. Added support for the Validation Criterion 2 ratio calculation and included the results in the T/HIS results table. ## **Bug fixes** 1. Made Clutch pedal an optional input for Automotive Assessment REPORTER templates. You are no longer prompted for missing Clutch Pedal input data. 2. Fixed an issue where selecting an entity with a comma in the title would be incorrectly considered invalid as commas were assumed to only be in part lists. 3. Fixed an issue where Occupant assessment graphs with no curves were deleted which meant that all subsequent assessments failed as they referenced a non-existent graph ID. 4. Fixed an issue where CSV data could not be imported. 5. In PRIMER, if an entity textbox contained a heading (or database history title) string that started with a number, the corresponding entity ID was incorrectly taken as the leading number characters which would lead to the incorrect entity being edited/sketched or a "does not exist" warning. Now fixed. 6. Fixed an issue where a capping limit asterisk was incorrectly being appended to the Euro NCAP MDB Shoulder Lateral Force assessment score when the limit had not been exceeded. # **Euro NCAP VTC Quality Criteria** ## **Enhancements** 1. Results generation is now significantly faster. 2. Entity selection improved to match Automotive Assessment methods and allows DATABASE_HISTORY headings as well as IDs. 3. The PRIMER GUI is now automatically pre-populated with any data found from Automotive Assessments. 4. For 10% Max Internal vs Hourglass curves, the Internal Energy curve is removed from the graph (if test is a pass) so that the critical Hourglass Energy curve is shown in more detail. # **Euro NCAP VTC Videos** ## **Enhancements** 1. Entity selection improved to match Automotive Assessment methods and allows DATABASE_HISTORY headings as well as IDs. 2. The PRIMER GUI is now automatically pre-populated with any data found from Automotive Assessments. 3. The three Shift Deform reference nodes have been changed to one Fixed reference node. 4. An Output Interval option has been added in PRIMER that sets the *DATABASE_BINARY_D3PLOT DT field to ensure output interval is 2 ms or less. 5. Added simulation start, interval and end time options to give more control over video export. 6. File size visibility added to the REPORTER Template so you don't have to search through your file system to check. 7. Euro NCAP Cut Section view now uses true thickness rather than fixed fixness. 8. New option added in PRIMER to allow you to blank parts such as the windscreen during video export. ## **Bug fixes** 1. The Cut Section view is now normal to the x-axis. # **LS-DYNA to ISO-MME** ## **Enhancements** 1. When writing out user data, the default Required output channel csv path is now written out using $OA_WORKFLOW to make the user data more portable across different machines. # **SimVT** ## **Enhancements** 1. The new, recently published ISO/TS 18571:2024 method replaces ISO/TS 18571:Euro NCAP v1.0. 2. The Correlation Setup window layout has been changed to landscape with a larger, clearer and more informative Channels Table. 3. Evaluation intervals can be controlled individually for each Sim vs Test model pair. 4. A Weight column has been added to Correlation Table window. 5. Channel selection from search improved. e.g. search for HEAD, select all, search for LUSP, select all. 6. Reverse button added to channel selection. 7. Evaluation interval from Head Excursion calculation is automatically applied to relevant Sim vs Test model pair. 8. Added support for multiple channel matching rules for same subject. 9. Added a derived channels counter to model hover text. 10. Updated the Protocol explainer text. 11. Improved the Channel Table update time. 12. Added ability to load new LS-DYNA models in to T/HIS from SimVT 13. Added functionality that enables SimVT to check if a new LS-DYNA model has associated Automotive Assessments Workflow Data (AAWD) and to assign AAWD to the new model. 14. Added checkboxes to the Model Mapping window so that only the selected rows will be loaded from the SimVT settings file. 15. Added labels to the Model Mapping window to make it clearer which entries correspond to "Reference (test)" and "Simulation(s)". 16. The Protocol option now defaults to "Euro NCAP Virtual Far Side v1.0" when SimVT is loaded as most users are expected to use SimVT for the Euro NCAP Far Side Validation Criterion 1 check. ## **Bug fixes** 1. The "Save SimVT settings" button is now disabled when no channels are selected, removing the possibility of saving invalid SimVT settings files. 2. Fixed an issue where Protocol change did not update model tag channels counter. 3. Fixed an issue where evaluation intervals saved to a SimVT settings file were not validated during reload. 4. Fixed an issue where ISO-MME or CSV data file was interpreted as an LS-DYNA model path if it was in the same directory as an existing Model in T/HIS. 5. The number of channels shown in brackets after the "LS-DYNA model" and "Imported Data" sources was not updated correctly when the Protocol option was selected. This has been fixed and more information is shown in data source hover text too. # **T/HIS CORA** ## **Enhancements** 1. The new, recently published ISO/TS 18571:2024 method replaces ISO/TS 18571:Euro NCAP v1.0. 2. Updated the T/HIS CORA tutorial to reflect the latest changes. ## **Bug fixes** 1. Fixed an issue where CSV export would omit some column titles.
