                          **Oasys 22.0 W1 Update**

This section lists all the changes made to **Workflows** since the Oasys 22.0 release.


# **Automotive Assessments**
## **Enhancements**
1. M23-181 - Renamed WSID 50M dummy supplier from "PDB" to "DYNAmore-PDB" to make it clearer that the dummy is from DYNAmore and co-developed with the PDB consortium.
2. M23-377 - Support for HIII 5F Knee Displacement has been added.
3. M23-595 - Acceleration curves from LS-DYNA results can be derived by differentiating velocity curves (instead of raw acceleration output) by ticking the "Use dv/dt" option in PRIMER Automotive Assessments before saving user data.
4. M23-596 - Added support to locate and load femzip files in REPORTER templates when original D3PLOT results files have been deleted.
5. M23-671 - When the Occupant window is open, the main window is now inactive to prevent an invalid state if the user interacts with the main window while the occupant window is open.
6. M23-199 - Entity Picker "Select By SET_PART..." now works for SET_COLLECT.
7. M23-1309 - The file selector now defaults to the model's directory when saving workflow JSON data in PRIMER.
8. M23-1503 - Changed scoring value for WS dummy LOWER_NECK_EXTENSION to use Abs(Min) instead Max(Abs). Also renamed parameter from "Max" -> "Abs(Min)" to clarify the new behaviour.
9. M23-1544 - The main window is now hidden when opening occupants and structures windows to reduce screen clutter and make it easier to pick entities from the model window.
10. M23-1559 - Chest and abdomen compression for THOR and THOR3 dummies is now calculated using DC0, ANZ and ANY components where possible to be consistent with physical hardware. For older dummy versions, which do not support these sensors, the relative change of the N1 and N2 rib nodal displacements are use used (old method).
11. M23-1629 - Added pelvis X, Y and Z acceleration entitiy definitions to the HUMANETICS SID2-SBLD dummy occupant definition JSON files.
12. M23-249 - Added Humanetics SID IIs SBLD v.4.4.5 occupant json for both LHS and RHS variants.

## **Bug fixes**
1. M23-457 - Fixed the component definitions of chest and abdomen ribs deflection transducer (springs) in the in Humanetics SID IIs SBLD v.4.3.5 occupant json and corrected the default history titles for the LHS version.
2. M23-458 - Corrected occupant JSON for HIII dummies so that chest rotation is correctly calculated (in some cases the ISO code for the rotational spring was "DSX" but should have been "AN0")
3. M23-460 - Automotive Assessments REPORTER templates which require an input test file used to only accept lower case file extensions (e.g. ".mme", ".chn", ".csv"). This limitation has been addressed and case insensitive file extension matching is now used.
4. M23-478 - Corrected Euro NCAP Far Side Sled 2024 AC limits for Lumbar Shear and Axial Force which were incorrectly swapped.
5. M23-752 - Fix inconsistent colours incrementing for structures curves when not all Assessment Types are selected in T/HIS.
6. M23-381 - Modified the constants in the polynomial and linear equations for the calculation of chest compression in the Humanetics HIII 95M Dummy so that compression is positive, expansion is negative, and that both functions produce an output that has the same sign.
7. M23-1287 - Fixed issue where if the protocol version combobox selection would default to the first version when loading multiple the workflow with multiple models.
8. Now able to Sketch parts from entity selector popup
9. M23-1561 - Corrected Humanetics THOR 50M v1.9.2 C-NCAP.json occupant definition to use THOR3 (i.e. THOR + H3 Legs) product rather than THOR product.
10. M23-1561 - Changed driver from THOR to THOR3 for CNCAP MPDB 2024 protocol.
11. M23-1559 - THOR and THOR3 abdomen compression has been corrected to use the x displacement (DSX) component only. Previously, the resultant displacement (X, Y and Z) was computed which could result in an overestimation of the compression value.

# **VTC Videos**
## **Enhancements**
1. M23-185 - New textbox has been added in PRIMER GUI for Property Files Directory.
2. M23-187 - Example buttons added for all views, rather than a general help '?' button.
3. M23-498 - EuroNCAP inputs simplified, meaning less inputs are required and now modular with other protocols.
4. C-NCAP, EuroNCAP Frontal & EuroNCAP Far Side Workflows merged into one workflow called 'VTC Videos'. Added a dropdown box to change between protocols.
5. M23-499 - POST GUI redesigned for simplification and more help.
6. REPORTER Templates used to used reporter output location for property files, now REPORTER will use the Property files specified from the Property Directory from the Workflows saved data.
7. M23-1063 - Reintroduction of using three fixed reference nodes (shift deform) to hold vehicle in place, as well as keeping the option to just use 1 fixed reference node.
8. Added CNCAP O2O Protocol.
9. Added CNCAP Front AEB OOP load case.

## **Bug fixes**
1. 1MB was being calculated as 1,000,000 bytes, now correctly calculated as 1,048,526 bytes which fixes issue where it would complain a video is over 10MB if it was slightly under it for Euro protocols.

# **LS-DYNA to ISO-MME**
## **Enhancements**
1. O22-1552 - Test name now populated with default name using automotive assessments crash test and version.
2. O22-1562 - Updated number of digit after decimal point to 2 for all mass values. Also added "Calculate Mass" button in PRIMER which calculates struct mass for the parts.
3. O22-1351 - Added support for frontal VTC protocol channels export, virtual testing ref ID and subtype of tests.
4. M23-581 - Mass calculation in T/HIS workflow for mass of different parts now works using d3hsp/otf file rather than relying on D3THDT.
5. M23-595 - Acceleration curves from LS-DYNA results can be derived by differentiating velocity curves (instead of raw acceleration output) by ticking the "Use dv/dt" option in PRIMER Automotive Assessments before saving user data.
6. M23-878 - Added a "Check mass" button which pop up a window to show mass information. This way we can avoid saving mass information in user data as we always needs to overwrite in T/HIS which always reports correct value from d3hsp/otf file.
7. M23-1480 - Added new inputs according to 2026 version and disabled the non-applicable ones. Also updated workflow to output the MME headers accordingly.

## **Bug fixes**

2. O22-1560 - Removed functinality which gets platform name from d3hsp/otf as it was reporting platform on which LS-DYNA was built on rather than where analysis was ran. Platform name is now manual input in PRIMER workflow.
3. O22-1510 - Fixed extra slash for required output channel csv.
4. Fixed a bug where loading LS-DYNA to ISO-MME for first time when there is more than one model read in PRIMER, Test name was not getting updated.

# **SimVT**
## **Enhancements**
1. M23-595 - Acceleration curves from LS-DYNA results can be derived by differentiating velocity curves (instead of raw acceleration output) by ticking the "Use dv/dt" option in PRIMER Automotive Assessments before saving user data.

10. M23-1349 - Improved performance when loading large number of channels in SimVT.
11. M23-251 - Head offset curves from CNCAP test video data can now be imported from CSV instead of derived from head acceleration angular velocities which could give inaccurate results.

## **Bug fixes**
1. M23-1402 - Fixed issue where the sensor score was showing the score for the final sim vs test correlation when comparing multiple simulations against test.
