NEi Works™

---

NEi Works provides SolidWorks users with an embedded finite element modeling tool. It features the familiar SolidWorks look and feel for all menus and functions, providing seamless integration between design and analysis. NEi Works features true geometry associativity, which means your loads, boundary conditions and even meshes are updated interactively whenever changes are made in SolidWorks.

With Nastran being one of the most widely used solutions, SolidWorks users can now communicate their FEA data to most standard pre- and post-processors through support of the Nastran file format. This provides versatility to a product which is already easy to use and backed by the renowned Nastran solution.
