ANSYS Mechanical

ANSYS Mechanical software offers a comprehensive product solution for structural linear or nonlinear and dynamics analysis. The product provides a complete set of elements behavior, material models and equation solvers for a wide range of engineering problems. In addition, ANSYS Mechanical offers thermal analysis and coupled-physics capabilities involving acoustic, piezoelectric, thermal–structural and thermoelectric analysis.

Superior CAD Interface & Robust Meshing

ANSYS has provided native bidirectional integration with the most popular CAD systems for more than 10 years. Integration directly into the CAD menu bar makes it very simple to launch world-class simulation directly from a CAD system.

Since the ANSYS geometry import mechanism is common to all CAD systems, the user has the flexibility to work within a single common simulation environment while using multiple CAD packages.

ANSYS provides a wide range of highly robust automated meshing tools — from tetrahedral meshes to pure hexahedral meshes, inflation layers and high-quality shell meshes. Mesh settings like surface or edge sizing, sphere of influence, defeaturing tolerances and more can be set by the user.

Auto Contact Detection for Assemblies

ANSYS mechanical solutions automatically detect and perform setup for contacts or joints between parts of an assembly. The contact settings and options can be modified, and additional manual contact definitions can be added. Joints for flexible/rigid dynamics are automatically detected. Each contact or joint is easily identified using the graphical tools provided in the environment.

Comprehensive Element Technology

ANSYS structural mechanics software provides a large library of elements including beam, pipes, shells, solids, 2-D planar/axisymmetric and 3-D axisymmetric elements, which have wide applicability that includes composites, buckling and collapse analysis, dynamics analysis, and nonlinear applications. The library also includes special-purpose elements like gaskets, joints, interface elements and layered elements for composite structures.

These elements offer superior performance and functionality. They also support advanced material models and methods like remeshing/rezoning, fracture mechanics and coupled fields while also accommodating distributed solver processing needs.

Extensive Library of Material Models

ANSYS provides a vast library of mathematical material models that aid the user in simulating various kinds of material behavior, such as elasticity, viscoelasticity, plasticity, viscoplasticity, cast iron plasticity, creep, hyperelasticity, gaskets and anisotropy. These constitutive models can be used to simulate various kinds of materials such as metals, rubber, plastics, glass, foam, concrete, bio-tissues and special alloys. In addition, to aid in finding parameters for these materials models, ANSYS provides a set of curve-fitting tools.

Advanced Numerical Methods for Nonlinear Problems

ANSYS structural mechanics offers various advanced modeling methods for different kinds of applications. There are modal, harmonic, spectrum, rotordynamics, flexible multibody dynamics, component mode synthesis, cyclic symmetry, delamination, composite failure, fracture mechanics, adaptive meshing, 2-D rezoning, submodeling, substructuring, element birth and death, and topology optimization, among others.

Powerful Solver Capabilities

ANSYS structural mechanics solutions offer a large library of out-of-the box equation solvers. The library contains the sparse direct solver, the preconditioned conjugate gradient (PCG) iterative solver, the Jacobi conjugate gradient (JCG) solution, etc. In addition, the distributed versions of PCG, JCG, and sparse solvers are available for use in large-scale computing via parallel processing.

Advanced Post-Processing

ANSYS provides a comprehensive set of post-processing tools to display results on models as contours or vector plots to provide summaries of the results. Powerful and intuitive slicing techniques allow the user to get more detailed results over given parts of the geometries. All the results can be exported as text data or to a spreadsheet for further calculations. Animations are provided for static cases as well as for nonlinear or transient histories. Any result or boundary condition can be used to create customized charts.


ANSYS provides instantaneous report generation to gather all technical data and pictures of the model in a convenient format (HTML, Microsoft® Word™, Microsoft® PowerPoint™).

Coupling Physics

ANSYS tools enable you to compute thermal–structural, thermal–electric, piezoelectric and acoustics impacts. Strong couplings use coupled elements that carry all necessary degrees of freedom.

Solver Customization & Scripting

Customization capabilities through user elements, user materials and scripting using ANSYS Parametric Design Language (APDL) provide flexibility and extend the capability of applications for mechanical solutions.

APDL is the foundation for accessing sophisticated features of the structural mechanics solver. In addition, engineers can use APDL to automate common tasks, build their own parametric models, perform design optimization, construct adaptive meshing, etc., as it offers many convenient features such as parameters, macros, branching, looping, and repeating and array parameters that can be used in day-to-day analyses.
