Overall: A hands-on CHT case walkthrough (electronics cooling example) — solid on workflow mechanics (CAD cleanup, fluid-volume extraction, materials, boundary conditions, convergence), thin on generalizable "best practices"; reads as a tutorial/webinar recap rather than a best-practices reference.

Video ideas:

  • CAD cleanup for CHT — what to simplify (connectors, imprints, small non-heat-emitting bodies) vs. what NOT to touch, plus inlet/outlet extensions to help convergence
  • The #1 CHT setup mistake — forgetting to extract the fluid volume as its own body, which silently assigns boundary conditions to the wrong domain; how imprinting fixes shared-surface heat transfer (tie-in: our conforming-CHT mesh avoids this class of error by construction)
  • Why a PCB conducts heat differently in every direction — anisotropic conductivity, series/parallel resistor-network analogy across copper/FR4 layers
  • How do you actually know a steady CHT run has converged? — probe-based convergence vs. our limitVelocity story
  • Reading flow physics from results — recirculation zones, low-flow dead zones, heat sinks misaligned with flow direction

Feature gaps:

  • Particle tracing / streamline visualization — flagged twice now (this article's "vector comets" recirculation view + the original note); no Feature Idea page yet, worth creating
  • Anisotropic (directional) thermal conductivity for layered materials (PCB case) — plausible gap, not yet verified against our code
  • Arbitrary per-body volumetric heat sources ("Power Source", W per chip/capacitor) — plausible gap, not yet verified against our code

Overall: Dry reference/feature-list documentation, not a tutorial — this is the actual source of most of the earlier "Features" bullet list. Useful as ground truth for what SimScale's Global Settings / Advanced Concepts actually contain, not for narrative content.

Video ideas:

  • Steady-state vs. transient/LES turbulence — why a steady-state h-estimator intentionally skips transient turbulence models (SimScale offers LES Smagorinsky as an option; we don't, by design)
  • Setting good initial conditions to avoid CHT convergence blowups — direct crossover with our limitVelocity gotcha

Feature gaps:

  • Rotating zones (MRF) for fan/impeller simulation — plausible real gap for electronics-cooling-with-fans use cases, not yet verified against our code
  • Momentum sources — related to rotating zones, not yet verified
  • Thermal Resistance Networks — likely overlaps with our existing Level-2 network model; needs a direct comparison, not an assumed gap
  • LES turbulence model — confirmed SimScale option we lack, but likely out of scope by design for a steady-only tool, not a real backlog item
