We are looking for an engineer who can run and troubleshoot an automotive cabin heating thermal comfort simulation using:
- Simcenter STAR-CCM+ (.sim) for cabin airflow/temperature fields - TAITherm Human Thermal / HTE + Berkeley Comfort for occupant comfort outputs
Task goal (what you need to deliver) We have a simplified cabin model. Under a cold ambient heating scenario, the current results are abnormal: occupant thermal sensation/comfort improves briefly and then becomes colder again (e.g., TS drops toward -1 and continues decreasing). We need you to diagnose the root cause and correct the model setup/coupling/mapping so the outputs are physically reasonable.
Target requirements (high level): - Transient duration: 1800 s (30 min) - Monitoring temperatures: foot/foot-vent zone around ~35°C, head point around ~20°C (exact monitor definitions will be shared privately) - Comfort trend: overall thermal sensation & comfort must be normal/stable (after heating ramps up, it should not “get colder again”)
What we expect from you - Identify why comfort trend becomes colder (typical causes include MRT/radiation boundary, incorrect field-to-human mapping of Ta/Tr/velocity/RH, initialization/restart issues, boundary leakage on cut surfaces, etc.) - Provide corrected settings + clear explanation of what was wrong and what you changed - Provide plots/outputs for monitoring temperatures + comfort metrics (TS/PMV/PPD or equivalent)
Required experience (please do NOT apply if you don’t have this) - Hands-on experience with STAR-CCM+ transient cabin HVAC/thermal - Hands-on experience with TAITherm Human Thermal / Berkeley Comfort (not only CFD) - Ability to actually run the case (access to software/licenses or a workable setup)
Confidentiality Due to confidentiality, we will share the detailed model files and full requirement document after you confirm capability.
Please answer these in your proposal:
1) Have you used TAITherm Human Thermal / HTE + Berkeley Comfort in real projects? Share 1–2 lines of what you did (no confidential details). 2) Do you have access to STAR-CCM+ and TAITherm comfort/human modules to run the model? (Yes/No) 3) List your top 3 likely causes when cabin heating comfort “gets colder again” (keywords are fine: MRT/radiation, mapping, restart/initialization, boundary condition, cut-surface leakage, etc.) 4) What is your estimated time (days) to deliver corrected results + explanation? 5）Tell me how much you would charge for my task.
