Digital modelling expertise

Numerical computation and simulation

Artelia’s teams excel in numerical modelling. Their expertise covers numerical models to aid the design of buildings and infrastructure, scientific computation software for uses in all of the group’s markets, as well as economic and logistics models.

Numerical computation and simulation

Artelia has at its disposal a library of software systems for performing design calculations in the fields of civil engineering, mechanics and geotechnical engineering, and complex numerical simulations in the fields of hydrodynamics, hydraulics, thermal engineering and the environment. These systems were developed in-house or in partnership, or purchased from developers.

Artelia distinguishes itself today through its ability to develop leading-edge, dependable software, its skills in complex modelling strategy, and its engineers’ experience in modelling software and environments to respond in the most suitable and reliable manner to its clients’ needs.

Artelia markets certain technical software packages in its fields of expertise, mainly in hydraulics, always adding significant value to the services it offers its clients through training, adaptation to new hardware configurations and assistance in using the software.

An example is the Canoe program used for hydraulics and hydrology studies in urban contexts, which Artelia has been co-developing for nearly 20 years in conjunction with the civil and environmental engineering laboratory of the INSA engineering school in Lyon.

Artelia is partner to Electricité de France with regard to the Telemac and Mascaret software systems and has been assisting with their development, distribution and promotion for the past two decades. Telemac and Mascaret are used to model flows, sediment transport processes, wave disturbance and water quality in continental and maritime aquatic environments.

In partnership with LEGI (laboratory of geophysical and industrial flows) and CERG (research and testing centre specialising in fluid mechanics), Artelia is working on the finite modelling of axial and cross flow water turbines, examining their downstream wakes and the impact of upstream turbulence on machine performance. The results obtained will be integrated into the Telemac system in order to model a complete array and define the optimum architecture for this type of scheme.

The BIM revolution, from buildings to regions

Building Information Modelling, or BIM, has revolutionised the design, construction and operation of buildings and infrastructure.
BIM computer platforms combine highly complex databases with a 3D digital representation providing a means of visualising a scheme (architecture, structure, network, facility, etc.) in all its dimensions. 

A building information model is a collaborative tool fed with data by architects, design engineers, project owners, material and equipment manufacturers, and is used to optimise the final performance levels of a structure and to build and operate it more efficiently while reducing the associated costs.

Artelia has been developing its use of these tools in the field of building construction for several years and now has solid expertise in digital mock-up design and BIM management, a new business line that is playing a vital role in enhancing communication between project stakeholders. 

The record of a million square metres of buildings designed using BIM was reached in mid-2015 and celebrated with the launch of an immersive visualisation system providing a means of stepping into and walking through the design of a future building.

Artelia has invested similar efforts in developing urban area modelling, reaching a milestone in 2015 with the handover of the 3D sustainable city simulator designed for Santiago de Chile. This process is continuing in the framework of several urban regeneration programmes.

A pioneer in the physical and numerical scale modelling of very large-scale hydraulic schemes, Artelia is also working on incorporating BIM into the water and environment fields.

Economic and logistics models

Artelia uses and develops economic and financial analysis and simulation tools adapted to projects, economic players and regions.
To optimise the design of particular projects, the group also has analysis and simulation tools for logistic flows at its disposal (the ARENA system in particular).
