5 Good Modeling Practices in Finite Element Analysis

Home » News » 5 Good Modeling Practices in Finite Element Analysis

The finite element analysis (FEA) is used to simulate the behavior of a part or assembly under given conditions so that it can be assessed. At Connekt LLC, our design engineers provide finite elements analysis consultation services to manufacturing firms in various industries to optimize components and reduce the requirement for physical prototypes.

Using mathematical models, our FEA experts analyze and quantify the effects of real-world conditions on parts and assemblies. We use specialized software to conduct simulations to locate potential problems in a design, including weak spots and areas of stress. Here are some good modeling practices our design engineers follow in finite element analysis:

1. Creating a Workable Plan

Before the finite element analysis begins, our design engineers thoroughly plan the analysis. We focus on the design objective, the best tool for product design, and the design criteria. Our engineers determine how much of the structure will need to be modeled and the boundary conditions. They analyze various aspects of the product that need to be estimated, like stability, frequency, stress, and displacement.

2. Understanding the Problem in Detail

Based on the objectives of the analysis, our FEA specialists run simulations to understand the detail of a problem. The FEA software usually provides an answer based on the set of equations for the simulation. To model a real structure and understand its behavior, you must understand the physics behind it first. You will then be able to replicate this behavior using a computer simulation. As a result, you can fully understand what your FEA is doing.

3. Selecting the Right Type of Analysis

Depending on the nature of the problem, you must define the type of analysis you need to analyze the effects of a product or part. The type of analysis depends on whether the problem is dynamic or static, linear or non-linear. The type of analysis you choose influences the assumptions you make during the modeling process.

4. Create an Understandable Mesh

For FEA to predict accurate results, meshing is a critical step. Our engineers run a simulation with a fine mesh to define critical regions of a model. Create a structured mesh in these regions and perform a convergence study to determine mesh density. As a result of meshing, discontinuities appear in the resulting mesh, known as cracks. Once the meshing process is completed, plot the edges using pre-processing software, check for deformation, and plot the mode shapes using modal analysis.

5. Verify and Validate Your Model

When doing FEA, even the most experienced engineers can easily make significant errors. Incorrect answers can sometimes lead to expensive decisions in terms of both time and money. To solve a problem using FEA, it is important to employ validation and correlation procedures and take FEA consultation services from a credible source like Connekt LLC.
