Structural analysis for every application and
experience level

Structural Analysis

Ansys structural analysis software enables you to solve complex structural engineering problems and make better, faster design decisions. With the finite element analysis (FEA) solvers available in the suite, you can customize and automate solutions for your structural mechanic problems and parameterize them to analyze multiple design scenarios. You can also connect easily to other physics analysis tools for even greater fidelity. Ansys structural analysis software is used across industries to help engineers optimize their product designs and reduce the costs of physical testing.

Structural analysis for all experience levels

From designers and occasional users looking for quick, easy and accurate results, to experts looking to model complex materials, large assemblies and nonlinear behavior, Ansys has you covered. The intuitive interface of Ansys Mechanical enables engineers of all levels to get answers fast and with confidence. Solve on your local machine or on the cloud. You can even run hundreds of design points using Ansys distributed compute services (DCS).

Reliable, high-quality, automated meshing

Mechanical has intelligent meshing technology so you can rapidly obtain optimal meshing on every model. Easily added controls enable you to fine-tune the mesh as needed.

Advanced capabilities

Simulation of complex materials and material behavior can be achieved using the built-in models, user-defined material models or Material Designer in Mechanical to create representative volume elements (RVEs). Models with very large deformation need not be simplified by switching to explicit solvers unnecessarily. The nonlinear adaptivity (NLAD) capability automatically handles challenging simulations by remeshing the solution as it progresses.

Splitting morphing adaptive remeshing technique (SMART) fracture technology has been added to Mechanical for modeling crack growth in structures where fracture is a concern, so complex meshing processes and guesswork can be eliminated.

Ansys Motion is a next-generation engineering solution based on flexible multibody dynamics within the Mechanical interface. It enables fast and accurate analysis of rigid and flexible bodies within a single solver. A series of toolkits provides extensions to Ansys Motion’s functionality so you can investigate the behavior of a vehicle’s powertrain design, including gears and bearings, and systems incorporating chains, belts and continuous tracks.

Additive manufacturing

Ansys provides a comprehensive, scalable software solution which minimizes the risk of your additive manufacturing processes and ensures high-quality, certifiable parts. With Ansys’ additive solutions, you can go from designing for AM (DfAM) all the way through part qualification and certification with the capability to do build-file preparation, metal AM build process simulation and material analysis at a microstructure level.

Complete structural analysis solution

A complete range of analysis tools is available to analyze single load cases, vibration or transient analysis; you can also examine linear and nonlinear behavior of materials, joints and geometry. Advanced solver technology with Ansys Autodyn and Ansys LS-DYNA enables you to carry out drop, impact and explosion simulations. Ansys AQWA, along with the offshore simulation capabilities in Mechanical, provides industry-specific capabilities for engineers designing marine environments.

System-aware IC power efficiency, power integrity and reliability

At the core of every electronics system is a chip that must meet multiple conflicting requirements, such as high performance, increased functionality, power efficiency, reliability and low cost. Ensuring the chip meets power efficiency, power integrity and reliability requirements as both a stand-alone component and within the electronics system calls for a system-aware chip design methodology. Ansys uniquely offers a suite of multiscale, multiphysics solutions to support a chip-package-system (CPS) design flow.

The Ansys semiconductor portfolio of power efficiency, power integrity and reliability solutions achieves ISO 26262 “Tool Confidence Level 1” (TCL1) certification. This certification enables automotive IC designers to meet rigorous safety requirements for ADAS and autonomous applications. Auto chip makers can leverage Ansys PowerArtist, Ansys Totem and Ansys RedHawk family of multiphysics simulations for all ISO 26262 safety-related development projects at any Automotive Safety Integrity Level.

Foundry certified accuracy

With the cost of designing and implementing a system-on-chip (SoC) ranging from $50 million to $200 million, first-time working silicon is a must. IC designers require the most accurate simulation solution and consider foundry certification as the ultimate proof of accuracy. Ansys semiconductor solutions have been certified by all leading foundries since 2006.

ANSYS Mechanical has all the tools you need to carry out the strength analysis of parts and assemblies. It has the ability to account for bolt-loading, stress caused by temperature variation and physical loads such as pressure, forces, moments, accelerations, and displacements. The response of the structure can be evaluated in terms of displacement, stress or strain ...

Thermal Analysis

Thermal management is a key concern in product design as the Internet of Things, wearable electronics and other product design trends condense heat-generating electrical components into smaller and smaller packages. ANSYS tools provide an environment for highly-accurate thermal simulation, including convection, radiation and conduction loads, as well as the effect of power losses and thermal energy from friction and other external sources.


Vibration and fatigue can severely impact maintenance costs and the life span of your products. ANSYS Mechanical solution and ANSYS nCode DesignLife analysis provide the integrated tools needed to identify potential vibration, mechanical and thermomechanical fatigue hotspots and improve product durability.


Mechanical systems often contain complex assemblies of interconnected parts, such as suspension assemblies in ground vehicles, robotics in manufacturing processes and landing gear in aircraft, Simulating the movement these systems is expensive, both in time and computational resources. ANSYS Rigid Body Dynamics provides a faster, less expensive and more efficient solution in the highly productive and easy to use ANSYS Mechanical.


Composite materials provide new solutions — and new challenges — for manufacturers looking for stronger, lighter and innovative materials. ANSYS Composite PrepPost, part of ANSYS Mechanical Enterprise, the software provides all the tools necessary for finite element analysis of layered composite structures.


Damage caused by collision or harsh environmental conditions can shorten a product’s life span, inflict warranty and repair expenses and incur liability risks. ANSYS structural analysis tools enable you to simulate mechanical, explicit dynamics and rigid body dynamics models to identify potential product deformation or damage after impact.


ANSYS Design Xplorer enables you to model multiple design parameters, different loading, and changes in environmental conditions in less than the time it takes to build a single physical prototype. Tools to identify then impact of each parameter and include manufacturing variability through 6 sigma methods. It enables you to perform all your simulations in a single environment, ensuring the best design for any condition.


Parallel processing with ANSYS HPC can significantly reduce solution time from days to hours, and makes possible large and extremely complex virtual models that were previously unfeasible. Designers can evaluate more design iterations in less time, speeding design optimization. Flexible and scalable licensing helps make HPC available to companies of any size.


ANSYS Mechanical gives you the tools you need to take advantage of new manufacturing methods like additive manufacturing. The optimal shape of a part is often organic and counterintuitive; ANSYS topology optimization technology lets you specify where supports and loads are located on a volume of material and let the software find the best shape. You can now easily ..


Additive manufacturing is a method of fabricating complex parts layer-by-layer from a 3D model. ANSYS additive manufacturing simulations help you to optimize your design for 3D printing, determine any potential stresses or distortions in the design so they can be corrected upfront, and predict the microstructure of the part based on the thermal history during fabrication.
