What’s New in Opera 2023

• The geometric modelling software used in the 3D Modeller has been upgraded to ACIS 2021. This provides improved interoperability with other CAD formats and changes to the surface mesh generator.
• In order to reduce the size of solved Opera-2d models, a new feature that allows users to save a subset of the solution cases has been introduced.

Acceleration Tokens, which are available as a Solver Process add-on for the SIMULIA CST portfolio licenses, can now be used in SIMULIA Opera 2022 in two ways:

• Opera-3d solvers can be made parallel for multi-threaded solutions. This use of an Acceleration Token is designed to speed up individual Opera-3d solutions by making use of multiple CPU cores to perform certain stages of the solution.
• Parameterized models can be run such that multiple solutions are run concurrently. Models which have been parameterized, so that several versions of the same model can be run to investigate a design, can now be run at the same time using Acceleration Tokens.

• Additional enhancements have been added to the Python API available in Opera-2d. This allows greater flexibility when working with Opera-2d solutions and creating automated processes.

• The licensed restriction on the number of threads that can be used by the Opera-3d solvers has been improved for users who have SIMULIA CST portfolio licenses. Multithread options are now included when solving using the Opera-3d solvers from the SIMULIA CST portfolio licenses. Additional parallel solving capabilities can be enabled using acceleration tokens.
