What are some tips for optimizing FEA models for computational efficiency?

To optimize FEA models for computational efficiency, simplify your geometry by removing unnecessary details and refining mesh density in critical areas. Use symmetry or periodic boundary conditions to reduce model size and computational cost. Employing simplified geometry not only speeds up analysis but also improves numerical stability and accuracy. By focusing computational resources on essential features and reducing unnecessary complexity, FEA models can achieve efficient and reliable simulations.

To optimize FEA models for computational efficiency, consider these key tips: Model Simplification: Simplify the model while ensuring it remains complex enough to provide valid results. Remove unnecessary details like fillets and rounds to improve mesh quality and simulation efficiency. Geometry Understanding: Before meshing, understand the geometry well to enhance the accuracy and efficiency of the simulation. Meshing Optimization: Increase mesh density at critical areas rather than uniformly across the model for more accurate results. Balancing mesh order and size is crucial for effective FEA meshes. By following these tips, you can streamline the FEA process, improve accuracy, and enhance computational efficiency in your models.

Some tips for optimizing FEA models for computational efficiency include simplifying geometry and mesh refinement, using symmetry and boundary conditions effectively, selecting appropriate element types and numerical methods, and utilizing parallel computing resources for faster simulations.

Having meanwhile a fair awareness about the Finite Elements Analysis, I do agree that, to optimize the FEA model we need to simplify the geometry as much as possible keeping the essential features and boundary conditions. For example, secondary elements simply supported on main elements, can be removed from the FEA model and its reactions will be reflected as loads on the supporting main elements.

we can choosing the proper mesh size and mesh order in structural model for optimizing the finite element analysis and improving the computational efficiency up to maximum extent

I do agree that the proper choice of the appropriate elements is an important factor that affects the computational efficiency of the FEA model. Element type, shape, order and size must be selected properly to suit the subject model and target objectives. A moderate number of elements in FEA model should be considered to reach accurate and stable results.

Use coarse meshes where possible without sacrificing accuracy, especially in areas with low stress gradients. Fine-tune mesh density in critical regions to capture complex behavior accurately.

Also, I do agree that to improve the computational efficiency of the FEA modeling at lower cost, the mesh should be refined enough to ensure the relevant features and phenomena of the subject model. This can be achieved through different techniques like using convergence studies, and the adaptive mesh refinement (AMR).
