R2019x Release: Established Products

By

The Simulation portfolio in 3DEXPERIENCE R2019x brings a variety of enhancements and new capabilities to all users, and analysts in particular can leverage a suite of Roles to connect existing models, data, results, and simulation IP to the 3DEXPERIENCE for structures (Abaqus), fluids (XFlow), and electromagnetics (CST). Below is an overview of what’s new in the SIMULIA Established products for the R2019x release:

Abaqus
