Within the 3DEXPERIENCE platform, we utilize SIMULIA for advanced simulation in industrial projects. Its seamless integration with CATIA on a unified data model ensures superior user experience and complete data integrity. We have successfully executed numerous linear and nonlinear static and dynamic simulations across key sectors, including automotive, marine, and rail transportation industries.
