FEA Process and Best Practices for Accurate Simulations

The effectiveness of Finite Element Analysis (FEA) lies in its process. A well-executed FEA simulation can provide accurate, reliable results, while errors in setup can lead to misleading conclusions. To ensure success, it’s essential to understand the step-by-step process of FEA and follow industry best practices. 

In this blog, we’ll break down the FEA process and highlight key practices that will help you achieve dependable outcomes in your simulations. 

The FEA Process 

Pre-Processing: 

• Import the CAD model. 
• Create a mesh using FEA meshing techniques to discretize the geometry. 
• Define material properties and apply boundary conditions. 

Solution Stage: 

• Solve equations like KU=FKU = FKU=F (stiffness matrix, displacement, and force vectors). 
• Compute displacements, stresses, and strains. 

Post-Processing: 

• Review results visually and numerically. 
• Validate the findings against experimental data or hand calculations. 

Best Practices 

Use Accurate Material Data: Incorrect material properties can render results meaningless. 

• Mesh Strategically: Avoid excessive refinement, but ensure critical areas are well-meshed. Validate Boundary Conditions: Misapplied supports or loads lead to errors. 
• Validate Boundary Conditions: Misapplied supports or loads lead to errors. 
• Check for Convergence: Ensure results stabilize as mesh density increases.
