Products - NEiWorks
|
NEiWorks 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. NEiWorks 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. [NEiWorks V1.2 New Features and Enhancements]

Assemblies. A nonlinear contact analysis of a plastic bearing assembly is performed. NEiNastran Editor. Use of the Editor feature for real time solution monitoring, direct modification of analysis parameters through the bulk data file, context sensitive help, and creation of custom plots. Composites. A composite bicycle frame model made up 2D orthotropic carbon weave material is created. Loads are applied and a static analysis is performed using a laminate element made up of multiple plies at various ply angles. Results are presented using various graphic visualization methods and the use of several failure criteria are illustrated.
