Euro NCAP Validation 

Euro NCAP VTC Simulation and Assessment Protocol Frontal Impact

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

Introduction

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

Section 3.3. The Validation cases are used both as the Sled loadcase as well as a way to test simulation data 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 Validation 1 or 2" 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 Validation 1 or 2 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 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 2.5). 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.Knee score is not applicable for Virtual Tests. However, unlike Euro NCAP Front Sled 2026 Robustness, the knee scores are not automatically removed from the score since Validation templates can be used with physical test data. 

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.

Validation Templates are more dynamic than the Euro NCAP Front Sled 2026 Robustness. They are intended to both be used with physical test data and simulation data. For the test data keep "Lower Leg Exceedance" modifier set to "Off" this allows lower leg scores to be scored. If the user instead wants to use virtual data, then select either the "Yes" or "No" option to set the leg score points with accordance to section 3.3 from Euro NCAP Frontal Protocol.

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

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:
