Do you need to complete a practical finite element analysis (FEA) to solve your engineering issue? This might be the solution you have been searching for, but you didn’t realize it existed.

So, what is it? A practical finite element analysis is used to solve issues with structure or performance. FEA models divide the structure into elements to analyze the system with extreme precision. Here’s how the process works.

## Three steps to FEA models

A practical finite element analysis uses a computer to model an engineering problem. It typically involves three steps:

• Defining the problem: The first step in FEA models is to express the problem that will be analyzed as a mathematical equation. If the problem is complex, this may involve creating multiple equations. The unknown factor that the equations are tempting to solve is a function of some kind.
• Crunching the numbers: In this step, the computer works to solve the equations. The factors are solved numerically.
• Post processing: Based on the solutions derived, additional quantities are computed. Visuals are created to represent values such as vector fields. Tables representing various quantities are generated and reviewed. Costs are also calculated and considered.

These steps are repeated, possibly many times, before the problem can be fully solved. The process is complete once the model fits the form and function that is desired or required for the application.

## Benefits of FEA models

Why would someone use a practical finite element analysis? FEA models allow more detailed analysis than is possible through hand analysis. They can be used in complex fields such as the aerospace and automotive industries to complete complicated analysis of large-scale models. Without FEA models, analysis of these systems would not be possible.

## Uses of practical finite element analysis

Thanks to the creation of FEA models, complex analysis has become common in many fields. A practical finite element analysis may be used in research, energy technology, reliability analysis, product design, virtual prototyping and computer-aided engineering. As technology continues to improve, and engineers provide innovative analysis solutions, more and more detailed analysis is possible in a variety of industries.

## Who can conduct a practical finite element analysis?

If you need to find an engineering solution that requires a complex analysis of your problem, you need the expertise of a structural engineer. There’s no need to stress and strain over the issue with attempts at hand analysis. These professionals have the knowledge, tools and skills to use FEA models to analyze the issue and generate feasible solutions. With their expertise, even the most complex problems can be solved.
