Hybrid multiphysics validation for multi-attribute engineering decisions

Modern engineering challenges are no longer confined to a single domain. Mechanical, electrical, thermal, acoustic and control behaviors interact continuously, and products fail not because one discipline is wrong, but because engineers discover trade-offs between disciplines too late. In electrified and software-intensive systems, success depends on the ability to validate interactions early and to balance competing attributes such as efficiency, noise, vibration and harshness (NVH), durability and controllability confidently. Simulation alone cannot capture every real-world effect. Physical testing alone cannot explore enough scenarios or design options.

Leverage Simcenter for hybrid multiphysics validation

Simcenter™ software solutions unify synchronized multiphysics data acquisition, advanced analysis, predictive system modeling, environmental simulation and real-time execution into a single hybrid workflow, where measured data and executable system models continuously inform each other. This transforms validation from a sequence of disconnected activities into a continuous learning loop. Engineers gain earlier insight into cross-domain interactions, teams converge faster on balanced solutions and organizations reduce late-stage surprises by grounding decisions in synchronized data and shared models.

Read this white paper to learn how Simcenter helps you:

• Capture physical signals across mechanical, electrical, acoustic and thermal domains with high fidelity and precise timing using Simcenter SCADAS™ hardware
• Correlate electrical behavior with structural response, acoustic outcomes and thermal evolution on the same time base in Simcenter Testlab™ software, without manual alignment or data duplication
• Explore architectures, predict energy flows, assess thermal margins and evaluate control concepts before hardware exists with Simcenter Amesim™ software, and estimate quantities that are difficult to measure through virtual sensing
• Represent road environments, maneuvers and tire-terrain interactions with Simcenter Prescan™ software so that validation is driven by realistic operating context
• Close the loop in real time with Simcenter Testlab RT, connecting executable system models directly to physical test benches for early system verification with limited or partial hardware

The white paper illustrates the workflow on a complete electric powertrain with torque, speed, acceleration, electrical, acoustic and temperature signals acquired synchronously. Engineers evaluate power efficiency maps alongside NVH indicators, correlate harmonics associated with inverter behavior with structural orders and acoustic response, and adjust control strategies with immediate visibility into their impact on efficiency, vibration and noise.
