AutoFEM Analysis is the friendly and easyinuse
software for finite element analysis
AutoFEM Analysis can be used by the broad community of engineers working in the field of mechanical and structural designing. You need not be a specialist in the finite element method in order to use AutoFEM Analysis. There are several askedfor modules, which allow for the solving of crucial problems for mechanical and structural engineering. They are as follows:
To make the use of AutoFEM Analysis easier, we have integrated our finiteelement solver with the most famous and used computeraided design (CAD) system in the world  AutoCAD (Autodesk, Inc. USA). Now each user of AutoCAD 20072010, 2012, 2013, 2014, 2015 and 2016. can perform the finite element modelling directly in the AutoCAD 3D environment. All that is necessary is to create a threedimensional (3D) model of the structure. Then you can immediately go to finite element analysis, using our builtin AutoCAD 3D FEA module. It is very easily and conveniently. You need not learn a new interface of the FEA program, because you remain in the AutoCAD environment. You need not perform export/import operations, because AutoFEM Analysis uses the same AutoCAD 3D model. The results of calculations can be saved in dwg file together with the main drawing. Your partner or customer can explore them using his/her computer system. It is fantastic, but it is true!
Moreover, there is one more exciting thing. There is AutoFEM Analysis Lite, which is absolutely free finite element analysis system. You can use it for educational and commercial purposes. Of course, AutoFEM Analysis Lite has some limitations related to the calculation capabilities, but they do not deal with the number of degrees of freedoms, as it normally occurs. This means that you can solve practical problems of your product.All that you need is to have AutoCAD 20072013, and download and install AutoFEM Lite. It is easy and worth doing!
We offer also AutoFEM Tutorial, which helps learn basic principles of work with AutoFEM.
Summing up the close integration of AutoFEM and AutoCAD, one can single out the following pluses:
The Native AutoCAD 3D Model Gives out the CAE Model
The CAE model is fully adequate to the design model, since it uses a native AutoCAD geometry. Finite element meshing is performed automatically and adaptively to the geometry of the 3D model.
Friendly and EasytoUse Interface
All commands of the finiteelement modelling are built in a standard AutoCAD interface. If you can create a 3D model in AutoCAD 3D, you can carry out its finiteelement modelling!
Wide Area of Application of AutoFEM Analysis
There is the vast package of various FEA modules of AutoFEM Analysis, which covers most important fields of engineering. Additional information is given below.
Static Stress Analysis
Static Stress Analysis is the most frequently used and calledfor FEA module. It is impossible to imagine a modern mechanical engineer which has no access to the finiteelement static analysis. The AutoFEM Static Analysis package has all necessary possibilities to become a daily instrument of the mechanical engineer and ensures the fast and easy testing of strength and durability of mechanical structures in manufacturing, building, shipbuilding and etc.

Fatigue Analysis
AutoFEM Fatigue Analysis module is used as an additional functionality of AutoFEM Static Analysis and allows one to test the strength of a structure subjected to a cyclic load. It is a very important type of loads in mechanical and structural engineering. This module is always provided with Static Analysis without any additional payment.

Frequency Analysis
Often, the mechanical engineer needs to know resonant frequencies of a structure. This knowledge allows one to make the design more reliable and satisfying demands of aerospace and automotive industries.

Buckling Analysis
This type of analysis is important for designers in the construction industry and planners of other very large mechanical structures, such as fuel tanks, bridges, towers, ships, etc. Sometimes, the structure, which was tested by the static analysis and proven to be reliable, may be destroyed due to primarily axial load due to of the loss of stability. This module is designed to calculate such critical loads.

Forced Harmonic Oscillations Analysis
As opposed to Frequency Analysis, which only determines supposed resonances, this module allows one to obtain the values of stress as well as safety factors when the structure is subject to force or kinematic external factors. You can get a conclusion about vibration strength of the structure.

Thermal Analysis
Often it is necessary to predict temperature fields which occur in the functioning structure. This module allows one to obtain distribution of temperatures in the structure as the function of time and in the steady state.

ShipConstructor integration module
This optional module is intended to give all users of the ShipConstructor software the opportunity to feel all advantages of the integrated finiteelement software solution. Using this module, ShipConstructor users can perform full cycle of engineering calculations (including strength, buckling and other analysis types) not leaving ShipConstructor software.
