About FEDEM

Welcome to the comprehensive world of FEDEM software, a powerful platform designed for the virtual testing and simulation of complex mechanical systems. Developed initially in the late 1970s by Professor Ole Ivar Sivertsen and continuously enhanced over the decades, FEDEM combines advanced structural dynamics with sophisticated control systems to offer an all-in-one solution for engineers and researchers.

What is FEDEM?

FEDEM stands for Finite Element Dynamics in Elastic Mechanisms. It is a technology platform and engineering framework that enables virtual testing of intricate mechanical assemblies. The software is particularly adept at handling nonlinear structural dynamics and integrating control systems within mechanical analysis. With its robust 3D graphical environment, FEDEM provides tools for creating, solving, and post-processing models, making it an invaluable resource for understanding the physical behavior of complex systems.

Applications of FEDEM

FEDEM is used across a wide range of industries and applications, including:

• Automotive: Suspension systems, axle systems, and car bodies.

• Aerospace: Satellite appendages and other high-precision components.

• Industrial Machinery: Robots, milling machines, and mechatronic systems.

• Medical Equipment: Devices that require precise dynamic simulations.

Creating and Using FE Models

A FEDEM model represents a virtual test model of mechanical systems, combining individual parts with finite element (FE) characteristics. These models are created using FE modeling software and imported into FEDEM for simulation. The software supports various file formats, including MSC.Nastran® and SESAM input files, ensuring compatibility with popular FE modeling programs.

Visualization and Post-Processing

FEDEM offers intuitive post-processing capabilities, allowing users to visualize results through curves, animations, and comprehensive stress analysis. This helps in gaining a clear understanding of the physical behavior of the model under different conditions.
