Finite element analysis overview (FEA)

SOLIDWORKS Simulation uses the formulation of the finite element method displacement to calculate the displacements, strains and stresses of the components subjected to internal and external loads. The geometry under analysis is subdivided using tetrahedral elements (3D), triangular elements (2D) and beam elements, then resolved through a Direct Sparse or iterative solver. SOLIDWORKS Simulation also offers simplification assumption for flat stresses, flat deformations, extruded entities and axisymmetric options. SOLIDWORKS Simulation can use an adaptive hop-type element, which provides designers and engineers with a significant advantage, since the adaptive method ensures the convergence of the solution.

For creating empty meshes, SOLIDWORKS Simulation offers an efficient tool called Emptying Management, which allows you to manage multiple emptying definitions in the part or assembly document. This tool allows to organize emptying according to type, thickness or material, improving the visualization and verification of the emptying properties.

Integrated in the SOLIDWORKS 3D CAD system, the analysis of the finite elements with SOLIDWORKS Simulation allows to know the exact geometry during the creation process of the mesh. The more the mesh matches the geometry of the product, the more accurate the results of the analysis will be.

Since most industrial components are made of metal, most FEA calculations are for metal components. Metal components can be analyzed by linear or non-linear stress analysis. The analytical approach to be used depends on the scope of the project:

If you want to verify that the geometry remains in the linear elasticity range (that is, that once the load has been removed, the component returns to its original shape), it is possible to apply the linear stress analysis , provided that the rotations and displacements are small compared to geometry. A common design goal of this type of analysis is the safety factor (FoS).

If you want to evaluate the effects of load cycles after yielding products on the geometry, it is necessary to perform a non-linear stress analysis . In this case, the main objective concerns the impact of hardening by strain on residual stresses and permanent deformation.

Non-metallic components (for example, plastic and rubber parts) must be analyzed using non-linear stress analysis methods , due to the complex load-deformation relationship that characterizes them.

SOLIDWORKS Simulation uses FEA analysis methods to calculate the displacements and stresses that occur in the product due to operational loads, such as:

-Strength

-pressures

-Accelerations

-temperatures

-Contact between the components

-Loads can be imported from thermal simulation, flow and motion studies to perform multiphysics analysis.

-Definition of mesh

SOLIDWORKS Simulation offers the functionality that allows you to create mesh of the CAD geometry with tetrahedral elements (first and second order), triangular (first and second order), beam and strut-tie. The mesh can be made up of a single type of elements or multiple types of elements to create mixed meshes. Solid elements are ideal for large models. The emptying elements are ideal for creating models of small parts (for example, sheets), while the beams and struts are particularly suitable for creating models of structural elements.

Because SOLIDWORKS Simulation is seamlessly integrated into the SOLIDWORKS 3D CAD software, the geometry topology is used for the mesh type:

The emptying mesh is automatically generated for model bodies and sheet surfaces

The beam elements are automatically defined for the structural elements

Therefore, the mesh properties are used seamlessly for FEA analysis.

To improve the accuracy of results in a given region, you can define the local Mesh control for vertices, points, edges, faces, and components.

SOLIDWORKS Simulation uses two fundamental checks to evaluate the quality of the elements in a mesh:

Verification of the perspective report

Jacobian points

If an error occurs while creating a mesh, SOLIDWORKS Simulation displays an error diagnostic tool to identify and resolve problems. The Mesh Failure Diagnostic tool displays faulty parts in shaded mode in the graphics area.

SOLIDWORKS Simulation can use an adaptive hop-type element, which provides designers and engineers with a significant advantage, since the adaptive method ensures the convergence of the solution. Product designers can analyze internal mesh elements with the mesh sectioning tool to control the quality of the internal mesh and make changes to the corresponding settings before running the study.

Users can specify local mesh control at the vertices, edges, faces, components and beams for a more accurate representation of the geometry.

Integrated in the SOLIDWORKS 3D CAD system, the analysis of the finite elements with SOLIDWORKS Simulation knows the exact geometry during the mesh creation process. The more the mesh matches the geometry of the product, the more accurate the results of the analysis will be.

-Definition of the mesh

SOLIDWORKS Simulation offers the possibility to create the CAD geometry mesh with tetrahedral elements (first and second order), triangular (first and second order), beam and rod elements. The mesh can be made up of a single type of elements or multiple types of elements to create mixed meshes. Solid elements are ideal for large models. Shell elements are ideal for modeling small parts (eg sheets), while beams and rods are particularly suitable for modeling structural elements.

Because SOLIDWORKS Simulation is seamlessly integrated into the SOLIDWORKS 3D CAD software, the geometry topology is used for the mesh type:

The shell type mesh is automatically generated for sheets and surfaces

The beam elements are automatically defined for the structural elements

Therefore, the mesh properties are used directly for FEA analysis.

To improve the accuracy of results in a given region, it is possible to define the local control of the mesh for vertices, points, edges, faces and components.
