Dassault Systèmes is a leading provider of 3D design and various simulation software, featuring solutions that enable complex processing and management on the same platform named the "3DEXPERIENCE Platform". The 3DEXPERIENCE platform connects an organization’s entire ecosystem – people, ideas, data, and processes, using a single unified environment. It combines knowledge and know-how using a unified data model and ontologies, supports all disciplines and acts as a single version of the truth. As a unified collaborative environment, the platform brings together all participants and enables secure, real-time collaboration on any device. Today, we will introduce simulation tools, especially Electromagnetic Field Simulation.
