About the UNIT/ Unit Overview
EG-411
You will be responsible for preparing CFD-ready STL geometries from CAD data for uFX-based simulations in two areas: vehicle exterior aeroacoustics and HVAC (heating/air-conditioning units). The focus is on robust, high?quality model preparation in ANSA and/or HyperMesh, not on running simulations.
Location
Pune
Experience:
6-10 years (maybe less if experience is there)
Number of openings

2 (1 for HVAC, 1 for Aeroacoustics),
Target Start latest Oct. 2026. The earlier the better.
What awaits you/ Job Profile
- Prepare and clean complex CAD assemblies (full vehicle exterior and HVAC components) for CFD, including de?featuring, leakage sealing and gap fixing.
- Generate high?quality STL surface meshes in ANSA and/or HyperMesh, tailored to aeroacoustic and HVAC flow requirements.
- Ensure mesh integrity and quality (no holes, overlaps,



non?manifolds; suitable element size, curvature and proximity control).
- Define and maintain consistent PID/part IDs and logical model structure for both exterior (body, mirrors, wheels, glass, underbody) and HVAC components.
- Split and export STL geometries into uFX-ready sets for exterior and HVAC use cases according to internal standards.
- Collaborate with CFD/aeroacoustic and HVAC simulation engineers as well as CAD/design teams to clarify geometry issues and ensure models meet project requirements.

What should you bring along
- Experience in CAD preparation and meshing (ANSA/HyperMesh)
- Good sense for CFD mesh quality and watertight geometry
- Ability to handle complex exterior and HVAC assemblies
- Structured, reliable and team-oriented working style

Must have technical skill
Ansa, HyperMesh or equivalent meshing tool
Valuable to have Technical skills
Python, uFX
