Nei Nastran In-CAD™

NEi Nastran in-CAD Features

Overview NEi Nastran in-CAD combines a FEM Modeler with comprehensive pre- and post- processing capabilities, and NASTRAN Solvers. Parts and assemblies can be analyzed for a wide spectrum of static, dynamic, and thermal loading. NEi Nastran in-CAD features true geometry associativity, composite elements, custom coordinate systems and nonlinear analyses for plasticity and true surface to surface contact.

With NASTRAN being one of the most  Dual Kernel Support and Kernel widely used solutions, NEi Nastran in-CAD collaboration (ACIS and Parasolid) users can now communicate their data to  Support both top-down and bottom-up most standard pre- and post-processors design process through support of the NASTRAN file format.
