NEiWorks

NEiWorks provides SolidWorks users with an embedded, state-of-the-art finite element modeling tool. It features the familiar SolidWorks look and feel for all menus and functions, as well as an automatic mesh updating feature when geometry changes are made. All loads and boundary conditions, along with material and element properties are associated directly with the geometry.

SolidWorks users can now communicate their FEA data to any Nastran solver, including NEiNastran, NX Nastran and MSC.Nastran. Results can be shared with any post-processor supporting OP2 or FNO binary results format.
