MODSIM — the new approach to collaborative design and simulation

The world moves fast. Shouldn’t your product development process move with it?

Product design in many industries relies on multiple cycles of analysis and physical prototyping. Innovation can only happen as fast as silos will allow it.

However, that’s all changing with MODSIM – unified modeling and simulation design.

MODSIM isn’t a single software solution or design tool. It’s an approach that significantly accelerates design exploration, optimization and validation thanks to the combined capabilities of CATIA®, SIMULIA® (including Abaqus) and cloud computing – all in the 3DEXPERIENCE platform on the cloud.

MODSIM expands creative possibilities and delivers high-quality designs, faster.

Go beyond simulation-driven design with MODSIM


Experience every aspect of your design. With MODSIM, engineers can concurrently check design performance and execute refinements and make better-informed design decisions, cutting the expense and time needed for analysis and physical prototyping.


Be more innovative than ever. Explore more design alternatives and optimize designs faster with capabilities like performance-driven generative design and the full power of Dassault Systèmes knowledgeware.



Expand your reach. Work across disciplines, regions and silos with a single collaborative environment for all aspects of product development available anywhere in the world, powered by Model-Based Systems Engineering and cloud computing.
