Finite Element Analysis for Mechanical and Civil Engineering

Finite Element Analysis (FEA)

Structural analysis uses the Finite Element Method (FEM) and related technologies to understand how products and assemblies behave under real-world loading and temperature conditions. 

With SIMULIA structure simulation technology, you can model virtual prototypes that help you answer many fundamental questions in advance of or as a replacement for physical testing such as:

  • Will my design perform as expected, and how can that performance be improved?
  • Will it break during service or due to mis-use? How will it break?
  • Will it leak?
  • How long will my product last?
  • How can I make it last even longer?

The new knowledge and know-how generated by answering these questions with finite element analysis (FEA) reduces costs, eliminates errors, and shortens design cycles. Unlike typical prototype testing, virtual prototypes can tell you much more than just pass/fail – it can tell you why a part will fail, and can help you understand whether your improvements will prevent it from failing. And unlike physical testing, mechanical simulation is available 24/7/365.

SIMULIA Structural Analysis Technologies

The SIMULIA portfolio in the structures domain includes Abaqus, fe-safe, and Tosca Structure technologies. Abaqus is a market- and technology-leader in linear and nonlinear finite element analysis. Both implicit and explicit solution techniques are available and are complementary. Fe-safe technology provides modern algorithms for durability and fatigue life cycle predictions. And Tosca Structure technology provides the ability to optimize the 3D shape and topology of your part to reduce weight and improve strength and stiffness. These technologies are well-known for their power, flexibility, feature set, and solution performance on modern HPC compute architectures including GPUs and Cloud.
