**Workplace:** on_site

**Department:** Weekday's Client via platform

## Description

**This role is for one of Weekday’s clients**

  
Min Experience: 2+ years  
Location: Bengaluru  
JobType: full-time

We are looking for a **CAE Model Build Engineer** with **2–5 years of experience** in crash simulation model preparation and finite element preprocessing. The ideal candidate will have strong hands-on expertise in **ANSA preprocessor, meshing, and crash model build**, with a good understanding of CAD geometry and LS-DYNA deck preparation.

The role involves converting CAD geometry into simulation-ready finite element models, building and modifying subsystems, ensuring proper connectivity between components, and integrating multiple subsystems into complete **LS-DYNA crash simulation decks**. The candidate will work closely with CAE, design, and simulation teams to deliver accurate, robust, and analysis-ready models within project timelines.

## Requirements

### Key Responsibilities

-   Perform **meshing from CAD geometry** using ANSA and create high-quality finite element meshes suitable for crash analysis.
-   Build complete CAE models from CAD data while maintaining appropriate element quality, mesh density, and geometric representation.
-   Create, add, modify, and replace **parts within existing subsystems** based on simulation and design requirements.
-   Ensure proper **connectivity between parts**, including appropriate interfaces, contacts, connections, and related model definitions.
-   Integrate and connect **two or more subsystems** to create a complete LS-DYNA crash simulation deck.
-   Perform model checks to identify and resolve issues related to mesh quality, free edges, penetrations, connectivity, duplicate elements, and disconnected components.
-   Support model preparation and updates based on engineering changes, design iterations, and simulation requirements.
-   Work with CAD geometry and engineering data to understand component interfaces and translate design intent into CAE models.
-   Prepare, modify, and maintain **LS-DYNA decks** as required for crash simulation activities.
-   Coordinate with CAE analysts and other engineering teams to resolve model-building and integration issues.
-   Follow established modeling standards, quality procedures, naming conventions, and project-specific guidelines.
-   Ensure timely delivery of high-quality crash models while maintaining accuracy and consistency across different vehicle or subsystem programs.

### Must-Have Skills

-   **2–5 years of relevant experience** in CAE model building, preferably in automotive crash simulation.
-   Strong hands-on experience in **model build for Crash** applications.
-   Proficiency in **ANSA preprocessor**.
-   Strong understanding of **meshing and finite element model build**.
-   Experience creating and modifying simulation-ready models from CAD geometry.
-   Good understanding of part connectivity and subsystem integration.
-   Ability to troubleshoot model quality and connectivity issues independently.
-   Familiarity with crash simulation modeling practices and engineering standards.

### Good-to-Have Skills

-   Practical exposure to **CAD geometry** and interpretation of engineering drawings/models.
-   Experience working with **LS-DYNA decks**.
-   Knowledge of LS-DYNA keywords, contacts, connections, and basic model setup.
-   Experience creating, adding, replacing, or modifying components within existing CAE models.
-   Exposure to automotive body, BIW, interior, or vehicle crash simulation projects.
-   Understanding of different mesh types, element quality criteria, and model validation techniques.
-   Ability to work effectively with cross-functional CAE and engineering teams.

### Qualifications

-   Bachelor’s degree in **Mechanical Engineering, Automobile Engineering, Aerospace Engineering, or a related discipline**.
-   2–5 years of hands-on experience in CAE preprocessing and crash model building.
-   Strong analytical and problem-solving skills with attention to detail.
-   Good communication and collaboration skills.
-   Ability to manage multiple model-building activities and deliverables within defined timelines.
