Oasys 21.0 is the latest release of the comprehensive LS-DYNA pre- and post-processing software. This latest version of the suite is designed to streamline processes and increase your productivity.

Whether you’re in engineering, design, or research, the suite’s automation capabilities ensure that repetitive tasks are handled efficiently, freeing up valuable time for innovation and problem-solving.

Key highlights:

Advanced automation and seamless integration with existing processes through JavaScript enhancements and our new Python API.

Building on top of the existing end-to-end workflow capabilities including extensive protocol support, multi-window environment and the power to submit jobs directly to LS-DYNA, Oasys 21.0 introduces further key Workflows which provide an easy, ‘out-of-the-box’ method to setup and run loadcases automatically.

One of the standout features of the suite is its focus on delivering quality models and results. With robust simulation capabilities and advanced analytics, the Oasys LS-DYNA Environment offers highly accurate correlation and analysis controls for Virtual Testing and extended multi-physics related features, including battery modelling.

The Oasys Suite provides complete LS-DYNA support, including the latest keywords and advanced crash and safety analysis tools, and enables greater collaboration with non-CAE users through automatic report generation and 3D results.
