AutoFEM Analysis Lite is a system of finite-element analysis. AutoFEM Analysis is a system of finite-element analysisThe main feature of the system is its deep integration with AutoCAD

AutoFEM Analysis Lite offers an easy to use first step analysis tool for every AutoCAD user. It is available for every user of AutoCAD at no cost. AutoFEM Analysis Lite uses the same finite element technology that a commercial version of AutoFEM Analysis. AutoFEM Analysis Lite is used to perform all kind of finite element analysis: -Static analysis -Frequency analysis -Buckling analysis -Thermal analysis

AutoFEM provides easy to use yet strong design analysis tools for designers and engineers that help them improve design quality, avoid field failures, reduce material costs, and shorten time-to-market. AutoFEM add-on software is integrated in AutoCAD and performs static, frequency, buckling and thermal analysis. AutoFEM makes it possible to perform design iterations quickly and inexpensively on computer models instead of on costly physical prototypes.

AutoFEM offers a wide spectrum of strong tools to help engineers to perform virtual testing and analysis for predicting the physical behavior under various loading conditions.

Fully integrated with AutoCAD modeling program AutoFEM allows you to test a design and run multiple iterations without ever leaving AutoCAD.

AutoFEM utilizes the AutoCAD Model Tree, Properties dialog boxes, command and menu structure, and many of the same mouse and keyboard commands, so anyone who can design a part in AutoCAD can analyze it without having to learn a new interface. Plus, since AutoFEM uses native AutoCAD geometry, design changes made in a model are automatically updated for analysis calculations.

Regardless of industry application, from aerospace to machine-tool, AutoFEM provides significant product quality benefits; enabling engineers to go beyond hand calculations and verify proof of concept for their designs. Quick and inexpensive analysis often reveals non intuitive solutions and benefits engineers by providing them with a better understanding of product characteristics.

Field failures can lead to costly recalls and liability issues. AutoFEM shows how a model will perform under real-world conditions before it is built. The capability to perform quick and inexpensive design iterations prior to releasing the design has become a critical competitive advantage. AutoFEM enables designers to meet functional design specifications but not waste materials helping to reduce cost of production, shipping, and packaging.

All calculations rely on the finite element method (FEM). At the same time, an associative relationship is maintained between the three-dimensional model of a part and the finite element model used in calculations. Parametric notifications of the original solid model are automatically propagated into the meshed finite element model.

Static analysis allows calculating the state of stresses and strains in a structure under the impact of constant in time forces applied to the model. It is also possible to account for stresses building up due to thermal material expansion/contraction, or for structural deformations introduced by known displacements. By using the "Static analysis" module, the user can evaluate the strength of a structure developed by him, with respect to admissible stresses, identify the most vulnerable parts of the structure and introduce the necessary changes, optimize the design.

Frequency analysis allows calculating natural (resonant) frequencies of a structure and the respective vibration modes. Based on the calculation results, the product is assessed on the presence of resonant frequencies in the operating frequency range. The developer can enhance reliability and performance of a product by optimizing the design in such a way as to exclude resonance occurrences.

Buckling analysis is important when designing structures, whose operation implies lasting influence of loads ranging in intensity. With the help of this module, the user can evaluate safety margin by the so-called "critical load". Significant nonelastic strains may occur suddenly within compressed parts of a structure, which could likely cause its rupture or serious damage.

Thermal analysis is the module providing the ability of evaluating a heated product behavior under the impact of sources of heat and radiation. Thermal analysis can be used independently for calculating temperature and heat fields through the volume of a structure, as well as in combination with static analysis for evaluating thermal deformations building up in the product.

AutoFEM Lite offers an easy to use first pass finite element analysis tool for every AutoCAD user. It is provided for every license of AutoCAD at no cost.

AutoFEM Lite uses the same design analysis technology that professional Analysis uses to perform all kind of finite element analysis:
1. Static analysis
2. Frequency analysis
3. Buckling analysis
4. Thermal analysis

But AutoFEM Lite has some limitations its functionalities such as kinds of the boundary conditions or some calculation features.

More advanced analysis abilities are available within the commercial AutoFEM line of products.
