Euro NCAP Robustness 

Euro NCAP VTC Simulation and Assessment Protocol Frontal Impact

This topic focuses on the automation of the Robustness (Virtual) Criterion (Assessment Criteria) assessment using REPORTER. 

Introduction

The Euro NCAP Front Sled 2026 Robustness REPORTER Templates can be used to perform the Robustness 1, 2 & 3 (Assessment Criteria) Euro NCAP VTC Simulation and Assessment Protocol Frontal Impact

Section 3.3. The Robustness cases are treated as the Virtual loadcases and are scored accordingly. For more information about scoring and methodology please refer to Euro NCAP Scoring and Colour Bands

Firstly, in PRIMER, you should have set up the occupant and structures required for your Simulation model. This can be found in Workflows in the tools menu, then Automotive Assessments and under the Crash Test dropdown find 'Front Sled', and for Version select "2026 Robustness 1,2 or 3" and fill out the occupants and Structures. Then save the created Workflows data using the Save to File or Save to Model buttons. For more information see the 'Automotive Assessments PRIMER' manual. Automotive Assessments PRIMER

Using the REPORTER template

Before using the REPORTER template, you should have defined the occupant and structures user data required for your model in PRIMER (see Automotive Assessments PRIMER for details).

In REPORTER, click the Automotive tab and then filter by Virtual Testing (under protection) & Euro NCAP (under regulation) and double-click Euro NCAP Front Sled 2026 Robustness 1,2 or 3 to open the template.

You will be prompted for the Simulation (.key) file. Once selected the REPORTER Template will run and produce the results.

REPORTER Results

Page 1: Contains all point totals for each occupant body region as well as the overall point total and the true point total. For more information on the colours, points and scoring please refer to Euro NCAP Scoring and Colour Bands. The user can change the point calculation in REPORTER to calculate Overall points (out of 5) or True points (out of 1.667 5/3). The two buttons below allow for switching between points in an active reporter session, the selection will result in all points adjusted along with relevant text. Load Case Points is shown in the image below, the default is to display Load Case Points. For more explanation of Loadcase Points and Overall Points please refer to Euro NCAP Points 

Superscripts:

1. Lower leg score points awarded by default unless in any physical test (including full-scale) any dummy exceeds the LPL or Tibia index or Tibia force.

This comes from section 3.3 in Euro NCAP Frontal Protocol. To toggle between leg scores receiving full points and leg scores receiving no points use the modifiers on page 2 of the template.

2. Knee score is not applicable for Virtual Tests

This comes from section 3.5.3 in Euro NCAP Frontal Protocol.

Page 2: Contains the subjective modifiers 

To turn on a subjective modifier just click on the "Set Modifiers" button and type "Yes" into the respective modifier box. The Template will automatically compute the new scores.

Pages 3 and 4: give a more detailed score overview for each occupant. The occupant is split into its respective body regions and criterion. 

The Lower Leg Max Values are presented only for the Users information. The Banded Scores are not coloured in to show that these scores are only for informational purposes the true score and point values come from the "Lower Leg Exceedance" modifier. 

Pages 5 - 44: Contain T/HIS graphs and plots of all the occupant and structure criterion 

Running in Batch

The template can also be run in batch mode, specifying the required information through command line arguments.

If your results are in the same directory as the keyword file then you only need to specify the keyword file on the command line and the test file and red zone which are specific to this template:

<reporter_exe> -batch -file=<template_name> -varKEYWORD_FILE=<keyword_file> -varTEST_FILE=<test_file> -varRED_ZONE=<red_zone> -exit

[Add the -pdf, -html, -pptx command line arguments to write the report out in the format you want]

Where:

If the results are in a different folder to the keyword file, you will need to add an extra argument to specify it:

<reporter_exe> -batch -file=<template_name> -varKEYWORD_FILE=<keyword_file> -varRESULTS_DIR=<results_dir> -exit

Where:

Similarly if you want to output the images and other files generated by REPORTER to a different folder than the default, you will need to add an extra argument:

<reporter_exe> -batch -file=<template_name> -varKEYWORD_FILE=<keyword_file> -varOUTPUT_DIR=<output_dir> -exit

Where:
