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.
An in-depth survey of 700 current and future users of 3D printing holds few surprises, but results emphasize some major trends already in progress. Two standouts are the big growth in end-use parts and metal additive manufacturing (AM) most respondents expect.
