Mastering CAE Simulation with SolidWorks: Your Step-by-Step Guide to Finite Element Analysis (FEA)

Computer-Aided Engineering (CAE) has revolutionized the engineering landscape, and SolidWorks is one of the leading tools for conducting CAE simulations. In this blog, part of Skill-Lync’s CAE Simulation using SolidWorks series, we’ll dive into the basics of Finite Element Analysis (FEA), explore various SolidWorks simulation tools, and explain how these simulations can benefit mechanical engineers and students alike. 

Understanding Finite Element Analysis (FEA) 

Finite Element Analysis (FEA) is a computational technique used to solve structural problems by discretizing a model into smaller elements. These elements are connected by nodes, and governing equations are solved to derive crucial results such as stress and strain contour plots. The process typically involves three steps: 

• Pre-Processing: Define material properties, discretize the model (meshing), and apply loads and constraints. 
• Solving: Use algorithms to calculate displacements, stress, and strain. 
• Post-Processing: Analyze and visualize results using contour plots and reports. 

Popular software for FEA includes SolidWorks, Ansys, and COMSOL, alongside open-source options like Code_Aster. However, Skill-Lync’s CAE Training emphasizes the user-friendly interface and robust analysis capabilities of SolidWorks CAE simulation tools. 

The Stress-Strain Graph and Material Behavior 

A fundamental aspect of FEA is understanding material properties, often represented through a stress-strain graph. This graph is derived from tensile testing and provides insight into material behavior under different load conditions. Key regions of the stress-strain graph include: 

• Elastic Region (O to A): Stress is proportional to strain, obeying Hooke's Law. The material regains its original shape upon unloading. 
• Plastic Region: Beyond the elastic limit, permanent deformation occurs. The upper and lower yield stress points mark the onset of plastic behavior. 
• Ultimate Stress Point: The maximum stress the material can withstand before failure. 
• Rupture Point: Indicates material breakage or failure. 

These properties are critical in SolidWorks stress analysis to ensure accurate simulation results. 

Static Analysis: Linear vs. Nonlinear 

Static analysis in SolidWorks is classified into two categories: 

• Linear Analysis: Assumes small deformations and constant material properties within the elastic limit. 
• Nonlinear Analysis: Accounts for large deformations, plastic behavior, and updated material stiffness with each iteration. Nonlinear simulations are computationally heavier but provide realistic results for complex scenarios. 

Skill-Lync's SolidWorks CAE Training covers both linear and nonlinear analyses, equipping students with the expertise to solve diverse engineering problems. 

Meshing in SolidWorks 

Meshing is a critical step in FEA, dividing a model into triangular or quadrilateral elements: 

• H-Refinement: Increases the number of elements, reducing their characteristic length. 
• P-Refinement: Maintains the number of elements but increases their order by introducing mid-side nodes. 

Accurate meshing is essential for reliable results. Skill-Lync’s SolidWorks CAE course provides hands-on training in meshing techniques, ensuring precision in every simulation. 

1D, 2D, and 3D Analysis 

Depending on the model's complexity, FEA can be performed in one, two, or three dimensions: 

• 1D Analysis: Used for models with one dimension significantly larger than the others, like beams. 
• 2D Analysis: Ideal for thin sheets or shell structures, offering a balance of accuracy and computational efficiency. 
• 3D Analysis: Used when detailed stress analysis of the entire model is required, despite higher computational demands. 

Skill-Lync SolidWorks Training includes practical examples to help students understand when to use each type of analysis. 

SolidWorks Simulation Modules 

SolidWorks offers various modules tailored for specific analyses: 

1. Static Analysis: For time-independent loads and stresses. 
2. Fatigue Analysis: Evaluates material behavior under cyclic loading. 
3. Frequency Analysis: Determines natural frequencies and mode shapes. 
4. Buckling Analysis: Assesses failure due to axial instability. 
5. Thermal Analysis: Studies temperature gradients caused by conduction, convection, and radiation. 
6. Optimization: Iterates design parameters for optimal stress or mass. 
7. Pressure Vessel Design: Customized tools for designing and analyzing pressure vessels. 
8. Drop Test: Simulates the impact of a model being dropped, using explicit time integration.
