Range of Analytical Tools Prepares Geometry Quickly and Gives You Confidence
Ansys Mechanical creates an integrated platform that uses finite element analysis (FEA) for structural analysis. Mechanical is a dynamic environment that has a complete range of analysis tools, from preparing geometry for analysis to connecting additional physics for even greater fidelity. The intuitive and customizable user interface enables engineers of all levels to get answers fast and with confidence.
Ansys Workbench enables robust connection to commercial CAD tools, providing click button design point updates. Seamlessly integrated multiphysics capabilities are available with fluids and electrical solvers.
Linear Dynamics
Ansys Mechanical covers all your needs for linear dynamic analysis, including modal, harmonic, spectrum response and random vibration with pre-stress, along
with advanced solver options for rapid solutions.
Carry out acoustics simulations to understand the vibroacoustic behavior of systems, with or without structural pre-loading. Including pre-loading adds more fidelity and means that self-weighted, bolted assemblies — or even squealing brakes — can be simulated.
Nonlinearities
Moving beyond linear, elastic materials, you can simulate the behavior of materials as they undergo plastic or even hyperelastic deformation (materials like rubber and neoprene).
Nonlinear simulation also takes into account contact and large deflection of parts moving around relative to each other, either with or without friction.
Contact
Ansys Mechanical includes a comprehensive range of contact capabilities that enable you to account for the interactions of multiple parts.
It can simulate everything from a bonded contact that treats joints between parts as if they are glued or welded together to contact interfaces that allow parts to move apart and together with or without frictional effects. Being able to simulate contact correctly means that you can simulate the change in load paths when parts deform and confidently predict how assemblies will behave in the real world.
Structural Optimization
Ansys Mechanical includes parametric, shape (mesh morphing) and topology optimization. Any model in Ansys Mechanical can be used to drive a parametric optimization.
Any model in Ansys Mechanical can be used to drive a parametric optimization. Shape and topology optimization capabilities allow creation of efficient geometries, which can be taken back to CAD for production or further simulation work. Additive manufacturing, lightweighting and robust design are excellent use cases for this technology.
Thermal Analysis
Simulating heat conduction, convection and radiation across assemblies enables you to predict the temperature of components, which can then be used to examine induced stresses and deformations.
With Ansys Mechanical, you can read in power losses or calculated temperatures from other analysis systems or files, which means that CFD or electromagnetic simulations can be a starting point for thermal analysis. It is also possible to account for fluid flow through pipes and heat generated from friction between parts. All these capabilities give you more accurate simulations and better results.
Materials
A range of material models covering everything from hyperelastics, shapememory alloys, soils, concrete, plastic and metallic structures can be accurately modeled in Mechanical.
You can also add user-defined material models, if needed. Granta Materials Data for Simulation provides instant, clickable access to the materials property data you need, eliminating data search time and input errors. Material Designer can easily create representative volume elements (RVE’s) based around lattice, fiber, weave or user-created geometries to facilitate multiscale modeling of complex material structures.
Composites
Ansys Mechanical includes capabilities to model short fiber composites taking data from upstream manufacturing simulation tools.
Ansys Mechanical includes capabilities to model layered composites through the connection with Ansys PrepPost (ACP) and short fiber composites through the connection with upstream manufacturing simulation tools and the material behavior obtained from Material Designer, the Ansys tool for multiscale homogenization of materials microstructures.
You can generate composite models for implicit and explicit structural, thermal and fluid simulations. Ansys Composite PrepPost (ACP) is the Ansys dedicated tool for modeling composite layups and failure analysis. ACP provides efficient layup and best-in-class solid element modeling capabilities and a platform that offers many ways to exchange model information. It supports the vendor-independent HDF5 composite CAE file format for communication with third-party tools, many of them dedicated and related to composites manufacturing. Beyond the modeling of composite structures, Ansys Composite Cure Simulation (ACCS), simulates curing during manufacturing processes. ACCS is an extension for Ansys Mechanical and it helps you to simulate the curing process of a part and predicts residual stresses and process-induced distortions for realizing compensation analyses.
Hydrodynamics (Ansys Aqwa)
Ansys addresses the vast majority of analysis requirements associated with hydrodynamic assessment of all types of offshore and marine structures.
These include SPARs, FPSOs, semi-submersibles, tension leg platforms, ships, renewable energy devices and breakwaters. Ansys Aqwa, has been used extensively in the oil and gas, renewable and general engineering sectors to model installation and use of equipment in open water as well as in harbors or sheltered locations.
Fluid-Structure Interaction
Accurately predict interactions between fluids and solids from pressure and/or thermal loads. As the fluid-structure interaction increases and the problem needs more detailed evaluation, Ansys has automated, easy-to use-solutions for both one-way and two-way coupling.
One-way coupling solves the initial CFD or Ansys Mechanical simulation and automatically transfers and maps the data to the other system. In a two-way coupling simulation, the fluid and structural simulations are set up and solved at the same time and data is automatically transferred between two solvers to achieve robust and accurate results.
Customization and Python Scripting
The fastest, easiest way to tailor your simulation workflows. Customization inside Ansys Mechanical enables repetitive tasks or specific workflows to automate and shared amongst users.
Journaling and python scripting capabilities enable quick development and easy education of new scripts.
APDL and MAPDL
Ansys Parametric Design Language, or APDL, is a powerful, structured scripting language used to interact with the Ansys Mechanical solver. Mechanical APDL, or MAPDL, is a finite element analysis program driven by APDL.
Both APDL and MAPDL can be used for various tasks ranging from creating geometries to setting up sophisticated solver settings for highly complex analyses. APDL provides access to advanced features and capabilities of Ansys Mechanical that may not be exposed or available through the graphical user interface (GUI).
With APDL, users can create custom input files, define material properties, apply boundary conditions and loads, customize the solution process, and more to tailor the analysis to their specific needs.
