Hot forging simulation predicts fill, press load, laps and die life before a die is cut. Flow stress and friction calibration, wear and heat checking, preform design, grain size, and where AI/ML helps.
Thermomechanical fatigue simulation predicts where start-stop cycles crack hot components. The physics of thermal stress, how CFD heat transfer sets the metal temperature, in-phase and out-of-phase cycles, and where AI/ML helps.
Power electronics thermal design for SiC and IGBT inverters: electro-thermal coupling, thermal impedance and RC models, cooler and spreading, thermomechanical FEA, and how mission-profile temperature swings become a lifetime estimate with AI surrogates and honest uncertainty.
Why aero-only optimisation misses blade vibration, how resonance, flutter, forced response and mistuning are assessed, and where machine-learning surrogates help carry aeromechanical margins into the design loop and where they cannot.
What acoustic-induced and flow-induced vibration are, how Energy Institute screening works, and how CFD, FEA and fatigue assessment confirm the risk and design the mitigation.
Have a model that will not converge?
Send the geometry, the physics and the decision it has to support. We answer with an approach, not a sales call.
