NEi Software has announced the addition of an explicit dynamics program to its simulation software suite, NEi Explicit 2010. This code has been used commercially since 2006, but has been enhanced by the lead developer, Dr. Lee Taylor, to meet the needs of NEi’s customers in the aerospace, automotive, and maritime industries.
NEi Explicit solves nonlinear impact problems that involve large deformations with complex contact and motion. Typical applications include crash, metal forming processes, drop tests, and ballistic scenarios. NEi Explicit can also be used to solve static problems with millions of degrees of freedom. Because they are extremely large and highly contact dominated, these problems are difficult to solve using implicit FEA codes.
Features of NEi Explicit include:
- Complete integration with the NEi Nastran environment
- Automatic contact generation
- Rigid materials definition
- Material deletion criteria with element deletion and automatic reconstruction of contact surface due to surface erosion
- Parallel performance
To help launch NEi Explicit, NEi Software will host an instructional webinar titled "When Nastran Goes Explicit" on Wednesday, Nov. 4 at 11 a.m. to 12 p.m. PST. The webinar will explain the differences between implicit and explicit FEA and demonstrate the use of explicit FEA through examples and applications using NEi Explicit.
