NEi Adds Explicit Dynamics To Simulation Software
NEi Software has announced the addition of an explicit dynamics program to its simulation software suite - NEi Explicit 2010. The code has been enhanced for 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. The animated solutions in the examples include a bird strike on a turbine engine, a bullet impacting armour, a sheet-metal stamping operation and fracture of a plastic buckle.
Key features of NEi Explicit complete integration with the NEi Nastran environment include: automatic contact generation; rigid materials definition; material deletion criteria with element deletion and automatic reconstruction of contact surface due to surface erosion; and parallel performance. NEi Software will host an instructional webinar titled 'When Nastran Goes Explicit' on 4 November at 11am-12pm 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.
