Strength analysis in the linear range (FEM)

Currently, the design stage is increasingly using FEM analysis in linear terms. The extensive portfolio of Autodesk software allows you to choose between Autodesk Inventor Professional, Autodesk Nastran In-CAD and Autodesk Simulation Mechanical.

Thanks to the Autodesk Inventor Professional software, we can create simple FEM analyzes. We can divide them into static analysis for one body and static analysis in the form of parametric dimensions. An additional advantage of using Autodesk Inventor Professional is the ability to import data directly from the dynamic simulation module.

Extensive material libraries are available in the software. In Inventor Professional, we have the Inventor library and the Autodesk library at our disposal. In Nastran In-CAD and Simulation Mechanical we get an additional library enriched with specialized materials.

When performing the FEM analysis, we must assume the boundary conditions. In Autodesk Inventor, we can choose a load such as force, pressure, bearing, moment, gravity and remote force. If you are interested in a time-varying load or a fatigue load, then choose Autodesk Nastran In-CAD or Autodesk Simulation.

The models analyzed by you can be defined as solids, beams, or surfaces. They have individual computational processes. The programs help you make the right choice. The big advantage of Autodesk Simulation Mechanical is a special calculation model for pressure vessels in linear ranges.

Autodesk Inventor has all the basic contacts such as related, separation and sliding. If you need a welded contact that has individual properties or thermal contact, then Autodesk Nastran In-CAD or Autodesk Simulation Mechanical is the perfect solution for you.


However, if you want to have a larger selection of mesh than the standard one in Inventor Professional, you should reach for Autodesk Simulation Mechanical. This program can create a hexagonal mesh. Such a mesh works especially well in thermal analyzes.

Autodesk Inventor Professional and Autodesk Simulation Mechanical allow you to perform FEM analysis in the linear range using the parameterization technique. This technique allows you to control the parameters of the model to obtain, for example, the minimum weight taking into account the allowable stresses. Using this function, we can explore an unlimited range of possibilities.
