Numerical simulation at the heart of the automotive industry

With the new regulations, the automotive industry has to constantly innovate to reduce product weight, fuel consumption and to improve product performance.
Our software meet the challenges of this ever-changing industry. They are well-known by world’s leading component producers serving the automotive industry and are already embedded in the design process to produce parts such as connecting rods, crankshafts, camshafts, drive shafts, pinions, steering knuckles, suspension arms, vehicle wheels, steering wheel, seats, etc.

Your main challenges

We help you with getting a head start in a highly competitive sector.


Ensure quality & reliability

Produce without trial/error and from the first batches of parts without defects and in accordance with technical specifications.


Intensify the weight reduction of components

Intensify the development of manufacturing processes for every lighter components as wells as for metallic materials (aluminium, HSS steel) than composite materials.


Engage in a Full Digital approach

Give yourself the means to simulate a multitude of processes involved in the manufacturing sequences to link process simulations to product simulations.

We meet your challenges

Every type of production presents its own challenges and we are here to provide specific answers to your different trades.

For forged components

Transvalor proposes key solutions to design parts “first-time-right” and shorten the time to market. From the quote phase, benefit from a solid solution to predict your deformation sequences, anticipate the defaults and delete trials/errors. Reducing production costs, you benefit from numerous advantages to increase your return on investment.


Forge svg (1)

FORGE® is a simulation software dedicated to hot-, warm- and cold forging processes.

Colform svg (1)

COLDFORM® is a simulation software dedicated to cold forming processes, and particularly suitable to manufacture fasteners. Designed on the basis of FORGE® software, it benefits from exactly the same level of reliability and robustness.

For cast components

Transvalor proposes an innovative solution for the casting of metal foundry parts. Thanks to the unique functionalities of its kind, the software THERCAST® stands out from the competition with a much more reliable prediction capacity for all defaults (shrinkage, porosity, cracks…) inherent in the process and able to intervene after filling and solidification.

THERCAST® is a software dedicated to the simulation of continuous casting processes, ingot casting and foundry processes.

For plastic components

Transvalor offers its REM3D® simulation solution dedicated to the shaping of polymers. For the automotive sector, REM3D® is particularly efficient at simulating the chemical foaming process of polyurethane foam used for the production of interior parts. Whether you are in the 'open mold' or 'closed mold' configuration, REM3D® optimizes the minimum quantity of material to be injected, the positioning of the vents, the inclination of the mold to see the effects of gravity on the filling. Steering wheels, seats or even acoustic panels are an integral part of the parts that you can fully study in order to improve your manufacturing processes.



Rem3d svg (1)

REM3D® simulates the injection processes for both traditional thermoplastics and reinforced plastics. REM3D is also one of a kind for simulating the chemical foaming process, simulating the phase of depositing PU foam followed by the expansion of the mixture by exothermic chemical reaction. This gives you access to the foam density mapping at any point of the molded component.

For welded metal components

Transvalor proposes its solution TRANSWELD® dedicated to welding processes including laser welding, Mig/Mag or Tig welding, with or without filler material, and also spot welding. Discover simple and effective solutions to test your welding settings and configurations. Anticipate recurring distortion issues, induced residual stresses and metallurgical transformation in the heat affected zones. TRANSWELD® will be your tool of reference to determine the best rates and the most adequate welding diagrams to optimise the cycle time of automatic installations.

Transweld svg (1)

TRANSWELD® is a numerical simulation software that predicts the thermomechanical behavior of an assembly during a welding process.The software also makes it possible to address the problems of mechanical strength of welded joints.

For heat treatment of metal parts

Transvalor offers its SIMHEAT® simulation solution dedicated to heat treatment for a wide range of metal alloys. Whether your automotive components are forged, molded, welded or even machined, the heat treatment step is essential to ensure mechanical properties that meet your customers' requirements. SIMHEAT® makes it possible to address both heat treatments in the mass (quenching, annealing, tempering, etc.) and surface heat treatments (carburizing, nitriding, etc.).


Simheat svg (1)

SIMHEAT® simulates the heat treatment processes of metal alloys and have a clear vision of the observed distortions on parts, residual stresses and microstructural evolution.

Case study NTN-SNR Roulements


Validate the induction hardening simulation process for the manufacturing of steel bearing rings.


By considering the characteristics of the current generator of the induction heating system, FORGE® software provides a major asset to precisely describe the entire process.



« The FORGE® solution is predictive because the parameters of the generator are used as they are as input data in the simulation for predicting the metallurgical properties of the part »
