Specialised in numerical simulation and the mechanical behaviour of structures, HEXAMECA supports its clients in their developments by providing high-performance finite element analysis solutions.

Particular attention is given to marine propulsion systems, with dedicated expertise in torsional vibration analysis (TVC) and shaft line reliability.

HEXAMECA mainly operates in the early stages of projects, during design and numerical validation phases.

Our engineering office is based in France, in the Morbihan region.

Torsional vibration calculations – marine propulsion

HEXAMECA performs torsional vibration calculations (TVC) for power transmission systems in the marine sector.

These analyses make it possible to identify critical speeds and to ensure that no excessive vibratory stresses occur in the shaft line, crankshaft, couplings and propeller under normal operating conditions.

This activity now represents the core of HEXAMECA’s expertise in the marine field.

Numerical simulation & engineering tools

HEXAMECA also provides finite element simulation services, hexahedral meshing of complex geometries and the development of dedicated engineering tools.

These capabilities enable the modelling of complex mechanical behaviours, the optimisation of designs and the development of tools tailored to industrial challenges.

They form the technical foundation of the torsional vibration studies carried out by HEXAMECA.
