Engineering Simulation Services

What Simwize Offers

Engineering simulation services at Simwize cover CFD, thermal analysis, system-level modeling, and reduced-order model development. Each project is scoped around the real engineering problem, so the simulation effort stays practical, focused, and useful for design decisions.

Thermal and CFD simulation for heat transfer and fluid flow analysis

Thermal and CFD Simulation

We perform 2D and 3D simulations of heat transfer and fluid flow for components and assemblies. The analysis helps identify temperature hotspots, pressure losses, flow imbalance, and cooling limitations before design decisions become expensive.

Typical applications include battery cooling, heat exchangers, electronics thermal management, and fluid-flow optimization. Simulations are performed mainly using ANSYS Fluent and OpenFOAM, depending on the project requirements.

Deliverables include validated simulation models, result reports, and design recommendations.

System-Level Simulation

We build system-level models that capture the interaction between thermal, fluid, and electrical behavior using OpenModelica or Simscape. These models help evaluate system performance, transient response, control strategies, and design trade-offs across different operating conditions.

This approach is useful when full 3D simulation is too slow or when complete system behavior is more important than local component detail.

Deliverables include system models, simulation studies, parameter studies, and performance analysis reports.

Digital Twin Development

We build data-driven digital twins of linear dynamic systems using reduced-order modeling (ROM), extracted directly from high-fidelity simulation, experimental, or test-bench data. Built on an open-source Python pipeline, models preserve key system dynamics while running fast enough for real-time applications, control development, and system integration. Works for any linear system with multiple inputs and outputs, regardless of domain.

Typical applications include battery thermal behavior, BMS integration, cooling-system response, and electro-thermal models, but the method applies to any linear dynamic system.

Deliverables include the reduced-order model, documentation, validation notes, and integration support.

Instructor-Led Training

Live, instructor-led training for engineers who want structured, hands-on simulation training delivered directly to their team. Sessions cover OpenModelica, Simscape, and system-level modeling, scheduled online or on-site to fit your team’s needs and timeline.

Topics include system-level simulation, thermal and fluid modeling, electro-thermal behavior, and real engineering use cases, tailored around your team’s actual applications where possible.

Online Professional Courses

Hands-on online courses for engineers who want to build practical simulation skills in OpenModelica, Simscape, and OpenFOAM. The training is focused on real model-building workflows, not only software menus or theory.

Course topics include system-level simulation, thermal and fluid modeling, electro-thermal behavior, validation, co-simulation, and practical engineering examples. The goal is to help engineers build models that are useful for design decisions, troubleshooting, and project work.
