Efficient, reliable model setup with support for all of the lastest LS-DYNA features.
Oasys PRIMER is the pre-processor designed to make preparation and modification of LS-DYNA models as quick and as simple as possible.
With support for every LS-DYNA keyword, you can read and write models with the confidence that no data will be lost or corrupted. The Oasys PRIMER user interface is designed specifically for LS-DYNA – with no compromises – giving you convenient access to a range of powerful pre-processing tools.
The Connections tool in Oasys PRIMER allows you to quickly and easily create welds, adhesive and bolted connections. You can import connections data from a spotweld file or directly from CAD, or create connections automatically using the geometry feature detection capability. Connection status can be reviewed in the Connection Table, where further modifications can be made. Once created, connections data are stored in the keyword file, allowing connections to be easily updated in future or used with other models.
Oasys PRIMER has a large range of checking functions. In addition to basic mesh quality checks, there are over 7000 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 errors 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 LS-DYNA output files. Entities with errors can be located on the model directly, making the task of debugging significantly easier.
Oasys PRIMER fully supports INCLUDE and INCLUDE_TRANSFORM files, and also has advanced tools for managing include files and label ranges.
The JavaScript and Macro functions provide you with powerful tools for creating your own scripts and interfaces for model generation and editing.
Oasys PRIMER has a number of tools to help you set up and position occupant dummies within a model. These include:
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.
Align crash barriers to test specification and automate pedestrian impact setup with step-by-step tools.
