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 solid 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
- Solid 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
