Westminster, CA. November 2, 2009. NEi Software ( www.NEiSoftware.com), a global provider of NEi Nastran Finite Element Analysis (FEA) software, announced the addition of an explicit dynamics program to their 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, specifically 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. Several examples of NEi Explicit applications along with product information can be found at www.NEiExplicit.com. The animated solutions in the examples include a bird strike on a turbine engine, a bullet impacting armor, a sheet metal stamping operation, and fracture of a plastic buckle.
Key Features of NEi Explicit
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
Compelling price point
To help launch NEi Explicit, NEi Software will host an instructional webinar titled "When Nastran Goes Explicit" on Wednesday, November 4th at 11:00 AM - 12:00 PM 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. Sign up for the webinar is at
