PRIMER

Our users choose PRIMER because:

• They can rely on it to maintain the integrity of the data
• They can find and fix errors easily before running LS-DYNA, avoiding wasted CPU time
• They can quickly and easily see and edit all the LS-DYNA data and understand the structure of the model
• The specialist tools such as spot welding, airbag folding and Part Replace are quick and easy to use
• Typically, with PRIMER, the time taken to assemble, modify and debug models is reduced by 80%; the percentage of error-free runs rises from 40% to 95%
• Models can be organized to allow teams to work efficiently in parallel on different components of the same model, with version control and automatic assembly of different crash load cases

• Miscellaneous

• Multiple model-build from impact target points
• Include file renumbering
• Coat
• Contouring
• Free Motion Headform
• Error Checking
• Keyword Editor
• Mechanisms and dummies
• Adhesive
• Bolt connections
• Spotwelding
• Tied contact for spotweld/adhesive
• Contact penetration check and fix
