NEi Explicit Software

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. It is completely integrated with the NEi Nastran environment, making the learning process much easier for Nastran users who are transitioning to an explicit solver. Existing Nastran users can directly analyze a Nastran implicit model in the NEi Explicit solver without any changes to the analysis file. The explicit architecture lends itself to highly scalable parallel performance, and large deformation contact solutions with highly nonlinear material behavior. NEi Explicit provides analysts with automatic contact generation, rigid materials definition, material deletion criteria with element deletion, and automatic reconstruction of contact surface due to surface erosion.
