Features & Benefits of FEA Simulation

 

1. Shorter Product Development Cycle

With Our FEA Simulation solutions, it can play an important part of your engineering design process by helping you to save precious project time and development costs by

1. Reducing completely the need for costly fabrication of physical prototypes and its subsequent iterations
2. Eliminating the need for manual rework and project schedule delays due to the delivery lead time of components.

Because of the speed & cost-saving benefits, Finite element analysis is often used early in the product development process to effectively show whether a product design will break, Wear out, or work the way it was intended.

2. Complete Structural Analysis Solution

We have a complete range of FEA simulation analysis tools available to help you analyze in detail

1. Single loading, Vibration forces or Transient loading conditions
2. Linear and nonlinear behavior of materials, joints, and geometry.
3. Simulation of Sudden Drop, impact, and Explosion (using Advanced FEA solver technology Autodyn and LS-DYNA)

If needed, we can customize and automate analysis solutions for your specific structural mechanic’s problems and parameterize them to analyze multiple design scenarios.
For even greater fidelity, our simulation software tools can also be seamlessly integrated to work with other physics analysis tools.

3. 2D/2 Dimensional Simplification

FEA Simulation also offers the 2D/2 Dimensional simplification approximation for Plane Strain, plane Stress, extruded features, or Axisymmetric options.
Beam Elements

Our FEA Engineers can help the simplifying of the modeling of various types of structural beams (such as Straight, Curved, and tapered beams) to optimize its performance in a Simulation environment.
* For a quick setup and modeling of the simulation analysis, structural members that are created as weldment features in 3D CAD are automatically converted into elements.

Type of Finite Element Analysis (FEA) Approach

The type of FEA analysis approach used depends on how far you want to push the design.
* As a majority number of parts designed for industrial applications are made of steel, most FEA simulations involves the use of various types of metal in the material input settings.
FEA simulation modeling of metal parts can be carried out by either Linear or Nonlinear stress analysis.

1. Linear stress analysis

If you want to ensure the component geometry remains in the linear elastic range (whereby the part returns to its original shape when the external load is removed), linear stress analysis methods can be applied, as long as the rotations and displacements are small relative to the geometry.
For such a simulation analysis, achieving a certain Factor of safety (FoS) requirement is a common design goal.

2. Nonlinear Stress Analysis

Nonlinear stress analysis is recommended for Evaluating the effects of post-yield load cycling on the part geometry.
In this case, the impact of strain hardening on Permanent structural deformation and Residual stresses is often the main focus of the analysis.
Nonlinear stress analysis is also ideal methods for the analysis of nonmetallic components (such as plastic or rubber parts) due to the complex nature of their Load-deformation relationship.
FEA Simulation uses FEA methods to calculate the deflection displacements and stresses in your product due to external operational loads such as:

● Solid elements are naturally suitable for bulky models.
● Shell element meshing are naturally suitable for modeling thin-walled parts (such as sheet metal components and surface bodies)
● Beam & Truss elements are suitable for modeling of Structural members.

Multiphysics analysis can also be performed by simply importing the loads from an existing thermal, flow, and motion Simulation studies

Finite Element Modeling

FEA Simulation uses the displacement formulation of the finite element method to calculate component displacements, strains, and stresses when subjected to internal and external loads.
The geometry under analysis is discretized using tetrahedral (3D), triangular (2D), and beam unit elements, and solved by either a direct sparse or iterative simulation solver.

FEA Simulation also provides the 2D simplification assumption for plane stress, plane strain, extruded or axisymmetric options. Our FEA Simulation software tools can use either an h or p adaptive element type, which provided a great advantage to engineers and designers because the adaptive method ensures convergence of the solution.
In order to streamline the model definition for Simulation purposes, FEA Simulation software automatically generates a shell mesh (2D) for the following geometries types:

1. Sheet metal body

FEA Simulation will assign the shell thickness according to the sheet metal thickness reflected in the 3D CAD data provided.

2. Surface body

For the shell meshing, our FEA Simulation offers a powerful Shell Manager tool, which is able to manage multiple shell definitions of your component or multi-part assembly.
This management tool helps to improve the workflow for organizing shells according to various characteristic parameters, such as Shell type, Thickness, or Material and enables for a better visualization and verification of shell properties.

Reliable High-Quality Meshing

An automated and intelligent meshing algorithms enable you to reliably obtain an optimal meshing on every 3D CAD model. This helps to ensure the generation of a high-quality meshing that is easy to accommodate additional local mesh controls for fine-tuning as needed.

Mesh definition

FEA Simulation offers you the flexibility to mesh the 3D CAD model geometry in either

1. Tetrahedral (1st and 2nd order)
2. Triangular (1st and 2nd order)
3. Beam, and truss elements. Depending on the Topology of the geometry, the mesh can consist of one single type of unit elements or multiple element types for a mixed meshing.
● Solid elements are naturally suitable for bulky models.
● Shell element meshing are naturally suitable for modeling thin-walled parts (such as sheet metal components and surface bodies)
● Beam & Truss elements are suitable for modeling of Structural members.

 

Adaptive Meshing Element

FEA Simulation can use either an h or p adaptive meshing element type, providing a great advantage to designers and engineers, as the adaptive method helps to ensure that the simulation solution converges. Engineers can evaluate the internal mesh elements with a Mesh Sectioning Tools to check the quality of the internal meshing and make adjustments to tune mesh input settings before running the simulation.

Local Meshing Control

For greater control during the meshing process, we also offer local mesh control to be defined at Vertices, Edges, Faces, Components, and beams for a more congruent representation of the actual geometry design. This higher meshing accuracy helps to provide a more accurate FEA simulation results in a particular region. As a form of quality check on the of meshing elements, we use Aspect Ratio Check and Jacobian Points to ensure that the final meshing is done correctly.
