Simulation
Design and simulation are key elements in the development of innovations in mechanics. This area, which is very cross-cutting, covers most of Cetim’s business divisions. The main challenges lie at two levels:
Integrate simulation and optimization into the design process;
coupling simulation and testing, to develop, validate and recalculate numerical models, define and customize tests to characterize materials, the behaviour of components and equipment, and qualifying their performance.
Product modelling and simulation lead to virtual optimization of solutions before physical implementation. Therefore, this trend is towards a more efficient way of design, taking into account the prediction of fatigue life and optimizing safety coefficients in a reliable approach. The main objective is to achieve much shorter development times.
Significant progress has been made in the simulation of increasingly complex and multi-physical phenomena.
This technological axis brings together projects concerning: the reliable design of products, the verification of functional requirements and the qualification of performance, analytical methods based on customer need, the design of clean and silent products, simulation of the behaviour and functioning of products.
As a key player in the industry of the future combining digital and mechanical expertise, we offer you the realization of calculation/simulation services and support in perfect alignment with your business requirements.
Our experts also contribute to the development of your employees’ skills through the integration of software tools in your company and dedicated training

Focus on Computational Fluid Dynamics services
CFD simulation helps to minimize the need for physical prototypes and tests while providing deeper insight into fluid flow design performance. Cetim is able to support a very complex project needing fluid-structure interaction if needed.
Flow Types: Steady / transient flows, Viscous / inviscid flows, Laminar / turbulent flows, Compressible / incompressible flows
Applications:
- Urban construction: Water and waste water, water hammering, aerodynamics of buildings, acoustic – NVH
- Automotive: Aerodynamics, engine combustion and thermal performance, acoustic – NVH
