CAE [computer aided engineering] analysis of NVH of ICE & Electric vehicles

Feels built by someone who’s actually shipped analysis to prod and dealt with the mess after, not just slides. The NVH arch choices get explained in terms of constraints, with Chapter 3’s order tracking walk-through on an inline‑4 coastdown sticking with me, especially how RPS normalization was handled before the FFT. There’s a practical thread on ICE vs EV differences, like the Campbell diagram example for gear whine, and how assumptions shift when there’s no combustion masking. The infra bits around parallel solvers and job orchestration were mostly clear; the concurrency angle here is strong without turning into theory soup. wasn’t sold on the brief CI mention tied to the repo workflow, and I wished there was more obs around correlating CAE to test mics. Still, it reads like someone who’s reviewed PRs under deadline and understands automotive NVH tradeoffs rather than lecturing from a whiteboard.

The logic behind the examples mostly held up when I sanity-checked them against my own CAE workflow. The order tracking vs FFT section in the ICE idle chapter stuck, especially the walkthrough showing the 3rd engine order popping at ~120 Hz and how that changed the mount stiffness sweep; I pulled the same notebook from the repo and ran it through CI without surprises. The parallel run approach for param sweeps felt unusually strong—mapping jobs across infra/k8s made sense and didn't feel hand-wavy. I wasn't sold on the brief e-motor inverter noise bit; could've used more obs around switching artifacts.

It felt closer to a hands-on walkthrough than a skim, which worked for an intermediate NVH CAE course. The EV motor section where you build a Campbell diagram and trace tonal orders stuck; I paused to sanity-check the mesh note before rerunning the example, and it lined up with what I’ve seen on automotive programs. I liked pulling the repo assets and comparing results, though I wasn’t sold on the brief ODS coverage and wished there was more obs guidance. Efficient way to add depth without bogging down.
