  • Part/assembly replace to update a model for design changes

  • Intelligent entity deletion with consideration for other dependent entities

  • Smart model merging with label clash resolution

  • Label management across multiple includes

Model Validation

  • Viewing of most LS-DYNA entity types allowing visual checking

  • Viewing of connections and relationships between entities (Cross-References and Attached)

  • Contouring of material properties, timestep, mass scaling, etc.

  • More than 9000 LS-DYNA specific checks with error tree view for easy identification and fixing of multiple instances of similar errors

Connection Definition

The Connections Tool in Oasys PRIMER allows you to quickly and easily create welds, adhesive and bolted connections. You can import data from a spotweld file or directly from CAD or create connections automatically using the geometry feature detection capability. The status of these can be reviewed in the Connection Table, where further modifications can be made. Once created, connection data is stored in the keyword file, allowing for use with other models or easy updates in the future. 

Model Checking

Oasys PRIMER has a large range of checking functions. In addition to basic mesh quality checks, there are over 9000 Ansys LS-DYNA specific checks to help reduce the amount of time taken to get a new model up and running. The Check Window and Error Tree Viewer allows users to clearly see any issues within a model and quickly locate the items that are causing the errors. As well as pre-processing checks, Oasys PRIMER is now able to scan the Ansys LS-DYNA output files. Entities with errors can be located on the model directly, making the task of debugging significantly easier. 

Include File Management

Oasys PRIMER fully supports INCLUDE and INCLUDE_TRANSFORM files and has advanced tools for managing include files and label ranges.

Scripting

The Python, JavaScript and Macro functions provide you with powerful tools for creating your own scripts and interfaces for model generation and editing.

Occupant Modelling

Oasys PRIMER has several tools to help you set up and position occupant dummies within a model. These include: 

  • Adjustable seat positions with Mechanism 
  • Pre-compressing seat foam 
  • Seatbelt fitting, including automatic refitting after dummy repositioning

Airbag Folding

Define the folding pattern for 2D and 3D airbags. Choose from a range of fold types such as thick, thin, tuck, spiral and scrunch. Distortion and penetration checking ensures the quality of the final folded airbag. Once created, the folding pattern data is stored in the keyword file to facilitate future modifications.

Barrier and pedestrian model set-up

Align crash barriers to test specifications and automate pedestrian impact setup with step-by-step tools.

Workflows

A growing library of tools to aid your workflows by helping you extract, visualise, and interrogate your LS-DYNA results quickly and efficiently, including Virtual Testing protocols.
