Products - NEiFusion

---

NEiFusion combines an FEA Modeler, pre- and post-processing capabilities, and Nastran solvers to create an analysis package for small and medium size companies, consultants, and any engineer who needs affordable, professional level simulation for product development, virtual testing, design validation, and quality assurance. Parts and assemblies can be analyzed for a spectrum of structural and thermal loading.

Why wait until prototypes are built, expensive test fixtures developed or actual field usage to find out how your design will perform? NEiFusion lets you apply forces, pressure, thermal conditions, temperature, vibration, and acceleration loads. You see the deformation, stresses, strains, heat transfer, and modal shapes that your design will experience. Through contour plots, deformations, and vector displays you get the engineering insight you need to innovate and optimize, so you can achieve the best quality, lowest manufacturing costs, and fastest time to market in today’s hyper competitive global marketplace.

NEiFusion Modeler. The NEiFusion Modeler is built on an industry proven, Windows based, fully associative, parameterized, feature based, solid modeling engine that provides a full set of advanced and powerful tools for fast, easy, intuitive, and robust model creation. A wide range of CAD data import capabilities complements the 3D modeling tools to help you build your models quickly when existing CAD files are available.

NEiFusion Pre-Processor. A utilitarian element library of solid, shell and composite, sophisticated meshing capabilities, and extensive material library insure you get real world fidelity and professional level simulation.

NEiFusion Nastran Solvers. NEiFusion employs the same industry regarded NEiNastran Solvers found in all of our analysis products so you can expect solutions that are accurate, precise, and reliable. Nastran assures that you achieve the best possible real world representation along with extremely fast turn around time on solutions.

NEiFusion Post-Processor. NEiFusion post-processing provides images of deformations, contours and vector displays to view your simulation results and also is equipped with wide file sharing and import/export capabilities so you can easily share your FEA results with vendors, design partners, suppliers, customers, and other segments of your organization. An important consideration in today’s highly collaborative work environment.

NEiFusion comes with a choice of solver packages.

NEiFusion employs the same industry regarded NEiNastran Solver modules ( L1 , L2 , L3 , L4 and L5 ) found in our flagship analysis product for solutions that are fast, accurate, precise, and reliable. However, please note that in NEiFusion, various analysis types and capabilities will be more limited depending on the level and configuration selected. The Solvers can be purchased individually or bundled in one of two popular packages.

Basic. This solver suite allows analysis and simulation of Linear Statics, Modal Analysis, Buckling, Prestress, and Steady State Heat Transfer problems.

Expert. This solver suite comes with all the analysis types in the Basic package and adds Nonlinear Analysis, and Transient Heat Transfer.

NEiFusion comes in two configurations: Designer and Analyst.

Designer Configuration: this is the lowest price option. The low price is achieved by coupling the NEiFusion Modeler and the NEiNastran solvers together so that they must be used together, that is, the NEiNastran solvers cannot be used with any other pre- and post-processors. If wider level analysis capabilities are ever needed, an upgrade option exists that enables conversion to the Analyst Configuration for unrestricted use of NEiNastran solver capabilities with other pre/posts.

Analyst Configuration: in this version, the NEiNastran solvers are independent of the NEi Fusion Modeler and are available to work with any other pre- and post-processors. The Analyst Configuration arrangement is useful in environments where multiple pre- and post-processors may be needed or are in use (e.g. NEiNastran Modeler, FEMAP, Patran, HyperMesh, ANSA, and others). Also, the Analyst Configuration includes the NEiNastran Editor. This feature enables additional post-processing capabilities, model data editing, and access to real time solution data.
