Structure-function measurement on the real package establishes junction-to-case resistance and the internal layer stack, while in-situ TIM characterization captures the interface as it is actually assembled. Those values calibrate the Flotherm model instead of being guessed from a datasheet, so board and enclosure predictions start from measured physics. HEEDS then explores heatsink geometry, airflow paths, and component placement across hundreds of variants, and the selected design is confirmed on Power Tester before release.

Design confidence from day one. Every model is validated. Every design is optimized. Every product is qualified.

Detailed 3D CFD resolves coolant flow, cell-to-cell gradients, and hot-spot formation inside the pack. Those results are reduced into Amesim system models so full drive cycles, fast-charge events, and cabin loads can be run in minutes rather than days. HEEDS optimizes coolant channel layout and control strategy together, the resulting model runs in real time against the BMS controller, and power electronics are characterized and cycled to failure to close the reliability loop.

More range. Longer battery life. Safer thermal management — before the first prototype.

A golden-reference structure function is recorded before cycling, so every later measurement can be compared layer by layer. Power cycling to AQG 324 runs with in-situ transient measurement, revealing whether Rth shift originates in die attach, substrate solder, or baseplate interface — and at which cycle count it began. Simulation is then re-correlated against the degraded stack so the next design revision targets the layer that actually failed.

Don't just qualify. Understand where degradation happens, how fast, and whether your design survives.

LED measurement separates radiant optical power from true heating power, so the thermal model is driven by the heat the device actually dissipates. FloEFD runs directly on the luminaire CAD geometry, letting designers evaluate housings, fins, and potting without rebuilding the model. HEEDS trades mass, cost, and junction temperature against each other, and accelerated cycling confirms the lumen-maintenance and warranty assumptions.

Cooler LEDs. Lighter luminaires. Longer life. Confident warranties.

High-fidelity CFD resolves convective film coefficients, plume radiation, and orbital heating without hand-tuned boundary conditions. Those loads transfer directly into the 3D thermal and structural solve, producing temperature-dependent stress and thermo-mechanical fatigue life on the same mesh. HEEDS then drives shape and material studies against margin, mass, and life targets in a single automated loop.

From temperature map to fatigue life to optimized design — one seamless workflow.

All industries with both design and thermal specialist teams

Designers run thermal checks inside their native CAD environment while geometry is still cheap to change, catching obvious airflow blockages and undersized heatsinks in the concept phase. Cases that survive that screen escalate to the specialist team with a defined question rather than an open-ended review. Specialists apply detailed solvers and HEEDS optimization where the physics genuinely warrants it, which keeps expert capacity focused on real risk.

80% of thermal issues caught by designers before they reach the specialist team.

Structure functions resolve each layer of the heat-flow path as a distinct thermal resistance and capacitance, so a void in the die attach appears as a measurable step change rather than an ambiguous overall Rth. A golden reference from a known-good part becomes the acceptance baseline for incoming lots and post-cycling screening. Because the measurement is electrical and non-destructive, the same part can be measured, cycled, and re-measured throughout qualification.

Component-by-component tuning produces locally good designs that fight each other at system level. HEEDS drives all three solvers inside a single search, so coolant loop sizing, duct geometry, and component placement are evaluated against one shared objective. Design-space exploration surfaces non-obvious combinations that no sequential hand study would reach, and every candidate is traceable back to the runs that produced it.

Optimize the whole system — not just one component at a time.
