Oasys Suite 20.0 released

Helping engineers achieve great results

Oasys Suite 20.0 is the latest release of the comprehensive LS-DYNA PRE and POST processing software. For many years, Oasys software has been helping engineers to power through their LS-DYNA workflow with all the tools required to simplify complexity and deliver results.

Our support for LS-DYNA is paramount, and the Oasys applications support all the latest features in LS-DYNA. Our comprehensive LS-DYNA checking tool ensures that all analysis issues are captured early on, saving time when deadlines are tight, and providing results you can trust.

This new version of the Oasys LS-DYNA Environment has exciting new features and updates within PRIMER, D3PLOT, T/HIS, REPORTER and SHELL to enable you to quickly produce high quality models and results.

Key highlights:

  • Many new additions and updates to automotive tools across PRE and POST processing, including pedestrian, occupant, and full crash models
  • New ‘workflows framework’ to link PRE and POST activities
  • New annotations functionality to make it easier to share results, insights, and solutions
  • Comprehensive support for new LS-DYNA data across your simulation workflow

Why choose Oasys Suite 20.0?

Quality models and results

The Oasys tools ensure the models you produce, and the results achieved, are high quality, error-free and credible. Model interrogation tools, such as “Find attached”, “Mass calculation”, cut-sections, cross-references and “Model modified” make it easy to inspect the detail of your models. The best-in-class model checking tool, alongside other checking tools – including load profile, decomposition, contact penetration, and element quality checks – make it quick to identify and correct any errors.

The powerful post-processing tools available within Oasys Suite 20.0 – such as “Shift deform”, force outputs, analysis and test comparison tools, and load path analysis – make it easy to gain insight into results and share with colleagues and collaborators.

Other Oasys Suite 20 features for quality models and results include:

  • Annotations in D3PLOT, to highlight and share key areas of interest. Annotations will also soon be available in D3PLOT Viewer, our web-based results collaboration tool
  • Further improvements to the cut-section tools across PRE and POST processing, to make it quicker and easier to view model data in the way you want
  • Improved support for User Defined Materials
  • Improved encryption tools to make it easier to create encrypted models and protect your data when sharing
  • GLB interactive models embedded directly in REPORTER templates

Complete LS-DYNA Support

LS-DYNA is at the heart of the Oasys Suite and Oasys 20.0 supports all the new features in the latest releases of LS-DYNA. This includes support for all keywords, including the latest keywords for the multi-physics solvers. Oasys Suite 20.0 makes it easy to work with relatively simple models, or the most complex LS-DYNA models, with complete support for *INCLUDE and *PARAMETER (in all their forms), IGA, LS-DYNA output file formats, as well as comprehensive label management tools.

We also provide high quality technical support and training to our LS-DYNA users worldwide.

For Oasys Suite 20.0, new features and functionality have been added to further support the entire LS-DYNA community, including:

  • Improved support for higher order elements
  • Support for new IGA LS-DYNA additions

Support across the whole LS-DYNA automotive workflow

The Oasys LS-DYNA Environment has always been at the leading edge of support for automotive engineers. Our comprehensive loadcase setup tools, such as “Crash Test Setup”, pedestrian mark-up, dummy/HBM positioning and belt fitting, mass calculation/distribution, and connection creation and management, are used by engineers worldwide to create quality automotive LS-DYNA models.

Our comprehensive post-processing templates provide an out-of-the-box solution for generating results for common loadcases, and our automotive-specific data analysis tools mean that processing raw data to produce the charts you want is quick and easy. Also, PRE and POST processing tools are closely integrated, to allow sharing of information and functionality to streamline the process of working across the entire workflow, from model creation to presenting and discussing results.

For Oasys Suite 20.0, new features and functionality have been added to further support the entire automotive LS-DYNA workflow:

  • More Human Body Models (HBM) supported and improved positioning functionality for HBMs
  • Improvements and additions to the Seatbelt Anchorage tool
  • Further additions to the pedestrian tools, including support of CAD models for markup, and additions to the HIC calculator tool
  • Seatbelt fitting updates, including auto-rotation of sliprings during positioning
  • Introducing a “Workflows” framework as an improved way of using LS-DYNA models across PRE and POST processing, including automotive assessments.

Automate your workflows

The Oasys Suite is fully customisable, and any tool or function can be incorporated into an automated workflow. The Oasys scripting API is a powerful way of extending features, introducing bespoke, organisation-specific functionality, and tapping into powerful functionality to use in new and innovative ways. This can be applied across PRE and POST processing, with model build and post-processing key areas for automation in the LS-DYNA workflow.

For Oasys Suite 20.0, automation and process integration features include:

  • New API additions and extensions, included new widgets to allow more feature rich bespoke GUI’s
  • New tool for automatically tracking analysis models created, and their history
  • New options for batch post-processing of multiple analyses
  • Introducing a “Workflows” framework as an improved way of using LS-DYNA models across PRE and POST processing, including automotive assessments



Speed, performance, and ease of use

LS-DYNA models continue to grow in size and complexity as the features available within LS-DYNA increase and more becomes possible using simulation.

The Oasys tools continue to support these increasingly large and complex models. Graphics speed, read/write speed, and check speed are all continuously improved with each release. D3PLOT Viewer provides an easy-to-use lightweight results viewer that allows anyone to interrogate LS-DYNA results, without the need for extensive training.

Oasys Suite 20.0 includes the following enhancements that make it easier to work with LS-DYNA models:

  • Oasys software technical manuals are now more accessible, with Google translate built in and improved search capabilities – visit help.oasys-software.com
  • Customisable menus to suit your individual way of working
  • New REPORTER template format to contain more embedded media

Other highlights:

  • Meshing updates to improve remeshing during HAZ connection creation
  • New measure features, including Node-to-Line
  • Assign mass “dry run” addition
  • CORA correlation tools additions
  • Method for linking human model trees and mechanisms – provides the ability to position ATD’s and HBM’s on bicycles and interactively move pedals/limbs realistically
