CAE Modeler - Senior

Actalent Services; Chennai District; On-site; INR 900,000 - 1,300,000; Full time

Job summary

Actalent Services is seeking a CFD Meshing Engineer in India to develop high-quality meshes for transmission and driveline CFD studies. You will clean CAD data, wrap surfaces, and simplify geometry using ANSA to prepare models for CFD analyses focusing on lubrication and thermal management.

You will set up flow domains, rotating regions, and boundary conditions, ensuring mesh quality meets solver requirements for Fluent, StarCCM+, PowerFLOW, and Converge.

Qualifications

• CFD meshing for transmission/driveline components.
• Collaborate with CFD analysts to produce robust meshes.
• Troubleshoot meshing issues and geometry defects.
• Adhere to modeling standards and best practices.
• Support multiple concurrent CFD projects to ensure on-time delivery.

Responsibilities

• Perform CAD cleanup, surface wrapping, and geometry simplification for transmission and driveline components using ANSA.
• Generate high-quality surface and volume meshes for CFD simulations (lubrication, oil churning, splash lubrication, thermal management).
• Set up flow domains, boundary conditions, and rotating region meshes (MRF/sliding mesh) for driveline components in ANSA.
• Collaborate with CFD analysts to translate model requirements into simulation-ready meshes.
• Troubleshoot and resolve meshing errors and geometry defects; maintain documentation of standards.

Job description

• Perform CAD cleanup, surface wrapping, and geometry simplification for transmission and driveline components (gearbox housing, differential, clutch assembly, oil pump, seals, bearings) using ANSA.
• Generate high-quality surface and volume meshes (tetra, poly, hex-dominant) for CFD simulations related to lubrication, oil churning, splash lubrication, and thermal management studies.
• Set up flow domains, boundary conditions, and rotating region (MRF/sliding mesh) meshes for driveline components in ANSA.
  Ensure mesh quality metrics (skewness, aspect ratio, min/max angle, growth rate) meet solver requirements for tools such as Fluent, StarCCM+, PowerFLOW, or Converge.
• Collaborate with CFD analysts to translate model requirements into robust, simulation-ready meshes.
• Support multiple concurrent transmission/driveline CFD projects, ensuring on-time delivery of high-fidelity models.
  Troubleshoot and resolve meshing-related errors, negative volumes, and geometry defects.
• Maintain documentation of modeling standards, best practices, and process checklists
