5. Added C-NCAP Far Side (+VTC) Protocol which comes with the following REPORTER Templates:
   • CNCAP Far Side Protocol 2024 Working Conditions 1-6 with Correction Factor A
   • CNCAP Far Side Protocol 2024 Working Conditions 1-6
   • CNCAP Far Side Protocol 2024 Working Conditions 7-8 with Correction Factor A
   • CNCAP Far Side Protocol 2024 Working Conditions 7-8
   • CNCAP Far Side Protocol 2024 Dual-Occupant Penalty (WSID Passenger)
   • CNCAP Far Side Protocol 2024 Dual-Occupant Penalty (WSID Driver)
   • CNCAP Far Side Protocol 2024 Dual-Occupant Penalty (ES-2re Passenger)
   • CNCAP Far Side Protocol 2024 Dual-Occupant Penalty (ES-2re Driver)
   • CNCAP Far Side Protocol 2024 Summary

Bug fixes

1. The DRIVER_HEAD_EXCURSION/HEAD_OFFSET curve may have been incorrect previously due to the following issue, which has now been addressed. Inputs to DRIVER_HEAD_EXCURSION/HEAD_OFFSET (i.e., acc x, acc y, acc z, ang vel x, ang vel y, and ang vel z) are now regularized to ensure consistent x-axis intervals. Afterwards, if the inputs are not of the same length (number of points), they are adjusted to match the minimum number of points among all input curves.
2. When editing multiple parts via the entity selector popup, a window would appear which would incorrectly say the next part to edit was the part ID that was just edited. This has been correct to show the next part ID.
3. When sketching entities via the entity selector popup previous sketches would persist if the entity type was different. This has been corrected so that everything is un-sketched before sketching a new entity.
4. The warning 'Dummy type xxx not supported in calculate_red_and_orange_lines' was being printed unnecessarily in T/HIS Automotive Assessments and is only relevant to the DRIVER_HEAD_EXCURSION assessment type. This issue has now been fixed.
5. The scaling to convert energy curves to Joules was incorrectly multiplying by the converison factor when it should have been dividing by it. This has been corrected.
6. If the model unit system and display unit system were set T/HIS would automatically scale curves to the display unit system and they would be scaled a second time by the conversion logic. To prevent this double scaling, the model unit system is unset before reading in new curves
7. Abdomen Force for ES2-re dummy was using the wrong sign convention so compressive force was negative. This has been fixed and now compressive force is positive.
8. REPORTER would freeze if it tried to write report outputs (images, curves etc.) with a file name that was too long for the Microsoft Windows operating system. This has been fixed by checking if files can be written safely before attempting to write them.

C-NCAP VTC Quality Criteria Tool Added

C-NCAP VTC Videos Tool Added

Ansys LS-DYNA to ISO-MME

Enhancements

1. Updated the tool to work with C-NCAP Far Side + VTC and Side Pole as per C-NCAP regulation.
2. Added Automotive assessments user data Crash test, Regulation and Version to show so user know for what protocol they are doing the export.

Bug fixes

1. Slightly shifted the custom date text box so it doesn't come on top of second radio button.
2. Changed the red colour for required inputs so that it matches with other workflows.
3. Removed default inputs for customer name, ref number and project ref number as it was saying EuroNCAP by default.
4. Now we report FS not FD. And I have changed text that said "nu" to "FS" now. We also now show "FD" and "DC" if DC is present as FD matters only if DC is present.

SimVT

Enhancements

Bug fixes

1. Fixed bug where the Ansys LS-DYNA models would not be found if relative paths were used when running the SimVT REPORTER templates in batch.
2. The HEAD_EXCURSION/HEAD_OFFSET curve may have been incorrect previously due to the following issue, which has now been addressed. Inputs to HEAD_EXCURSION/HEAD_OFFSET (i.e., acc x, acc y, acc z, ang vel x, ang vel y, and ang vel z) are now regularized to ensure consistent x-axis intervals. Afterwards, if the inputs are not of the same length (number of points), they are adjusted to match the minimum number of points among all input curves.
3. Hover text for plot corridor and correlation graph options has been removed as it was incorrect.
4. The scaling to convert energy curves to Joules was incorrectly multiplying by the converison factor when it should have been dividing by it. This has been corrected.
5. If the model unit system and display unit system were set T/HIS would automatically scale curves to the display unit system and they would be scaled a second time by the conversion logic. To prevent this double scaling, the model unit system is unset before reading in new curves
6. When loading a SimVT settings file, the max and min evaluation intervals were being overwritten by the defaults of the correlation method specified by the selected protocol. This has been fixed so that the values defined in the SimVT settings file take precedence.
   

T/HIS CORA

Enhancements

Bug Fixes

EuroNCAP Virtual Far Side 2024 VC2 Assessment Criteria Template

Bug Fixes

1. Max chest score when head is in the brown zone is corrected to 0 (was 2)

Euro NCAP Virtual Far Side 2024 VC1 (ISO Scores)

Enhancements

1. The summary page now shows the weights of each channel rather than the maximum signal magnitude

Bug Fixes

1. The operations from SimVT settings files were not being applied as intended. This has been fixed.

Pulse Index

Bug Fixes

1. Default value of Restraint stiffness was incorrect previously (was 2000 N/m). It is now corrected to 160,000 N/m, which results in the k/m ratio of 2000 s^-1.
