Fluid flow and thermal transfer simulations

Accelerate product innovation by enhancing fluid and thermal performance in the early design phase

1 | Inspire Innovation

In a typical design process for flow and thermal systems, designers or engineers create 3D models which are then sent to a specialist for CFD analysis and simulation. This typically takes several months, followed by physical testing.


Fluid Dynamics Engineer is tailored for engineers who perform routine fluid flow and conjugate heat transfer calculations to guide design improvements while exploring innovative design concepts.


It enables users to quickly explore hundreds of designs while concurrently improving product performance based on criteria such as optimal flow distribution, efficient thermal management, minimal pressure losses, flow uniformity or reduced recirculation.

The solution leverages industry standard RANS based finite volume Computational Fluid Dynamics (CFD) technology, with a fully guided user experience. This allows designers and engineers – even simulation novices – to innovate simulation-driven designs.


With Fluid Dynamics Engineer, simulation technologies are integrated with CAD and PLM, leveraging a single collaborative environment in the 3DEXPERIENCE platform on the cloud for end-to-end product development. High-performance computing capabilities on the cloud generate powerful, fast performance that doesn’t depend on local hardware resources.

2 | Accelerate time-to-market

Innovation has never been more important. With a manual approach to design, the ability to innovate is limited based on experience – what you’re familiar with and what you’ve done in the past.

Fluid Dynamics Engineer makes innovation faster and easier with a guided user interface, automatic fluid extraction and meshing, DOE and optimization studies, and a fully automated design exploration process.

The dedicated workflow guides users through the principal steps in a CFD and Conjugate Heat Transfer (CHT) simulation, so even novice users can set up and run simulations as needed.

Automatic fluid domain extraction makes it possible to reduce the complexity of internal fluid flow systems (pipes, valves and ducts) as well as external flows (buildings, vehicles). The automatic creation of a body-fitted hex-dominant mesh with boundary layers enables accurate CFD simulation concurrently addressing fluid flow and thermal transfer.

Stop relying on known designs and physically testing multiple design models thanks to automated design exploration. Pre-select a small number of optimized designs for analysis, and run hundreds or thousands of simulation scenarios to guide the design process. Make informed design decisions based on your criteria for quality, innovation and cost.

  • Build, deploy and re-use fully automatable design exploration processes

3 | Simulation-driven design

3DEXPERIENCE automation for design exploration relies on Model-Based Systems Engineering (MBSE), a “system of systems” offering a more complete representation of physical systems. MBSE connects the dots between different aspects of product design, simulation, engineering and manufacturing using a single modeling language (SysML). Simulation data is fully integrated with design data to enable design exploration and optimization based on accurate CFD data.
