About NEi Explicit
NEi Explicit is a parallel explicit solver that is completely integrated within the NEi Nastran environment. NEi Explicit solves complex nonlinear material problems, large deformation contact problems, and very large multi million degree of freedom (DOF) static and quasi static models.
Plus, existing Nastran users can directly analyze a Nastran implicit model in the NEi Explicit solver without any changes to the analysis file. The NEi Explicit solver is well suited for these large types of nonlinear problems providing fast, robust performance because there are no matrices formed which means a small memory footprint for the model.
The explicit architecture lends itself to highly scalable parallel performance, and large deformation contact solutions with highly nonlinear material behavior.
