Thermal VDDV (CAE) Execution Engineer

Description

Hybrid Work Position :  This position does not require an employee to be on-site full-time to perform most effectively. The employee’s role enables them to work at a GM facility or off-site as frequently as needed or desired. In the USA, this is an employee who lives 100 miles or less from their designated, primary worksite.

This position requires an employee to be onsite every other week.

Thermal Execution VDDV (CAE) Engineer will be responsible for gathering information from different sources inside and outside GM, building and running analytical models, interpreting results for customers, attending development team meetings, and interacting with compartment integration teams.

This person will build, run, and interpret results from various CFD and 1-D models ranging from the front end to the whole vehicle or thermal system. The engineer will join a multi-disciplined team of engineers who perform airflow, vehicle thermal and 1-D thermal simulations of varying complexity to drive the design of vehicles.

Responsibilities:

  • Estimate powertrain heat rejection and establish air flow requirements for automotive type cooling systems and condensers

  • Size an air conditioning system and establish cooling capacity required

  • Evaluate automobile exterior with focus on front end cooling air flow and sealing

  • Evaluate PTC and AC system performance using 1D and 3D simulations tools

  • May also do vehicle level thermal models or subsystem thermal models using 3-D CFD with heat transfer

  • Pro-actively develop simulations for new programs based on vehicle content and functional objectives.

  • Clearly post process and interpret simulation results to identify current performance and develop areas of improvements

  • Daily use of several commercial CFD codes, 1D solvers and supporting software in Windows, LINUX/UNIX and HPC environment. These include ANSA, STAR-CCM+, SINDA-FLUINT, MATLAB SIMULINK. GT Suite and other Internal Codes.

  • Interface and collaborate with Studio and Engineering Teams, present numerical and visual data and recommendations to ensure component and system level performance requirements are achieved

  • Fully engage in vehicle development activity and proactively take ownership of simulation activity to best guide the design team.


Additional Description

Required Skills and Experience:

  • 3+ years of professional automotive experience.

  • Experience and coursework in Lumped-Parameter Network Solvers, CFD methodology and application

  • Familiarity with Aerodynamic and Climatic Wind Tunnel testing, measurement techniques and data systems.

  • Experience using commercial 1D solvers such as MATLAB-SIMULINK, SINDA-FLUINT, GT-Suite, and CFD solvers such as FLUENT, STAR-CCM+, EXA-POWERFLOW, Mesh generators such as ANSA, TGRID, HYPERWORKS.

Preferred Skills and Experience:

  • Mathematical modeling and analysis of various subsystems of both conventional and electric vehicle powertrains using innovative analytical tools, including GT-Suite, MATLAB/Simulink in co-sim environments.

  • Experience with computer tools, 3D CAD files, CAE methods and Experimental Data

  • Experience with 3D CFD modeling and heat transfer included

  • Experience in design/release of automotive thermal systems

  • DFSS training, Green Belt

Education:

Bachelor’s degree in Mechanical or Electrical Engineering with coursework in Thermodynamics, Heat Transfer, Fluid Mechanics and Finite Element Analysis required.

Masters or Ph.D. in Mechanical Engineering focusing on Thermal Sciences preferred.

For GM INTERNAL CANDIDATES: This role is posted at both the 6th and 7th level. The determination by HR and the Hiring Manager as to whether an offer will be lateral or promotional will be based on a candidate's relevant experience and whether the role will amount to a significant increase in level of responsibility.
