Overview
Simcenter Systems Simulation is a 1D multiphysics system simulation platform by Simcenter that enables engineers to model, simulate, analyze and optimize complex multi-domain systems from early design through validation and operation. It supports heterogeneous simulation architectures and extends digital twin workflows to software engineering and real-time executable twins.

Key benefits

• Optimize system performance earlier in the design cycle to reduce development time and cost.
• Evaluate and balance multiple performance attributes across domains (mechanical, electrical, thermal, fluid, controls).
• Reuse and share models across distributed engineering teams to accelerate delivery and ensure consistency.
• Enable Model‑in‑the‑Loop (MiL), Software‑in‑the‑Loop (SiL) and Hardware‑in‑the‑Loop (HiL) workflows for controls development and validation.

Core capabilities

• 1D multiphysics system simulation platform with support for 1D/2D/3D coupling and multi‑domain components.
• Electrical and electromechanical system simulation for dynamic performance, consumption analysis and control law validation.
• Fluid and thermal system simulation for HVAC, thermal management, pipeline and distribution network analysis.
• Mechanical and multibody simulation including rigid/flexible bodies and nonlinear interactions.
• Propulsion and powertrain modeling for electrified and hybrid architectures across automotive, aerospace, marine and industrial sectors.
• Co‑simulation, PLM connectivity and FMI support for multi‑tool integration and streamlined workflows.
• Reduced‑order model (ROM) creation using machine learning and numerical reduction methods for real‑time executable twins.
• Collaborative model and data management with versioning, branching and role‑based access (Git client integration).

Engineers can

• Address the complexity of automated and electrified products by coupling multiple domains in one environment.
• Share and reuse validated models to reduce physical prototyping and speed time to market.

Typical use cases

• Vehicle thermal management, HVAC and cabin comfort systems.
• Powertrain electrification and controls calibration.
• Industrial cooling, Rankine cycles and energy recovery systems.
• Marine systems (ballast, fuel and environmental control) and shipboard power integration.
• Large distribution systems, pipelines and industrial gas networks.
