Ansys Mechanical

    Linear Dynamics

Ansys Mechanical provides comprehensive capabilities for linear dynamic analysis, encompassing modal, harmonic, spectrum response, and random vibration with pre-stress, along with advanced solver options for expedient solutions.

It is essential to conduct acoustic simulations in order to gain insight into the vibroacoustic behaviour of systems, whether or not structural pre-loading is present. The incorporation of pre-loading enhances the fidelity of the simulations, enabling the modeling of self-weighted, bolted assemblies and even the simulation of squealing brakes.

    Nonlinearities

By extending the scope beyond linear and elastic materials, it is possible to simulate the behaviour of materials undergoing plastic or even hyperelastic deformation (such as rubber and neoprene).

Nonlinear simulation also considers the effects of contact and large deflection of moving parts relative to one another, whether or not friction is present.

    Contact

Ansys Mechanical software offers a comprehensive suite of contact capabilities, which facilitate the incorporation of interactions between multiple parts within a single analysis.

Software is capable of simulating a wide range of contact scenarios, from bonded contacts that treat 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. Correct simulation of contact enables the analysis of load paths when parts deform, thus facilitating the prediction of the behaviour of assemblies in the real world.

    Structural Optimization

Ansys Mechanical software suite incorporates a range of optimization techniques, including parametric, shape (mesh morphing), and topology optimization. It is possible to utilize any model within Ansys Mechanical for the purpose of driving a parametric optimization.

It is possible to utilize any model within the Ansys Mechanical suite for the purpose of driving a parametric optimization. The capacity to optimize both shape and topology enables the generation of efficient geometries, which can then be transferred back to CAD for subsequent production or further simulation work. Additive manufacturing, lightweighting, and robust design represent optimal applications for this technology.

    Thermal Analysis

Simulation of heat conduction, convection, and radiation across assemblies allows for the prediction of component temperatures, which can then be employed to examine induced stresses and deformations.

Ansys Mechanical software enables the reading of data pertaining to power losses or calculated temperatures from other analysis systems or files. This facilitates the integration of CFD or electromagnetic simulations as a preliminary step in thermal analysis. Furthermore, the simulation can account for fluid flow through pipes and the heat generated from friction between parts. The aforementioned capabilities facilitate more accurate simulations and yield superior results.

    Materials

A range of material models covering everything from hyperelastics, shape-memory alloys, soils, concrete, plastic and metallic structures can be accurately modeled in Mechanical.

Furthermore, the option is available to incorporate user-defined material models, should the necessity arise. Granta Materials Data for Simulation offers immediate, direct access to the materials property data required, thereby eliminating the time required for data searches and reducing the incidence of input errors. The Material Designer is capable of readily generating representative volume elements (RVE's) based on lattice, fiber, weave, or user-defined geometries, thereby facilitating multiscale modeling of intricate material structures.

    Composites

Ansys Mechanical software includes the capability to model short fiber composites, utilizing data obtained from upstream manufacturing simulation tools.

Ansys Mechanical software includes the capability to model layered composites through the connection with Ansys PrepPost (ACP), as well as short fiber composites through the connection with upstream manufacturing simulation tools and the material behavior obtained from Material Designer, which is the Ansys tool for multiscale homogenization of materials microstructures.

Implicit and explicit composite models may be generated for structural, thermal, and fluid simulations. Ansys Composite PrepPost (ACP) is a dedicated tool within the Ansys suite that is designed for the modelling of composite layups and the analysis of failure. The ACP provides efficient layup and exemplary solid element modeling capabilities, as well as a platform that offers a multitude of avenues for the exchange of model information. Furthermore, it supports the vendor-independent HDF5 composite CAE file format, which facilitates communication with third-party tools, many of which are dedicated to and related to the field of composite manufacturing. In addition to its capabilities for modeling composite structures, Ansys Composite Cure Simulation (ACCS) is also capable of simulating the curing process during the manufacturing of composite materials. ACCS is an extension for Ansys Mechanical that facilitates the simulation of the curing process of a given part, enabling the prediction of residual stresses and process-induced distortions for the purpose of conducting compensation analyses.

    Hydrodynamics (Ansys Aqwa)

Ansys software suite is capable of addressing the vast majority of analysis requirements associated with the hydrodynamic assessment of all types of offshore and marine structures.

Such structures include SPARs, FPSOs, semi-submersibles, tension leg platforms, ships, renewable energy devices, and breakwaters. Our product, Ansys Aqwa, has been utilized extensively in the oil and gas, renewable energy, and general engineering sectors for modeling the installation and utilization of equipment in open water as well as in harbors or sheltered locations.

    Fluid-Structure Interaction

The ability to accurately predict interactions between fluids and solids from pressure and/or thermal loads is a crucial aspect of engineering analysis. As the complexity of the fluid-structure interaction increases and the necessity for a more detailed evaluation arises, Ansys has developed automated, user-friendly solutions for both one-way and two-way coupling.

One-way coupling is a solution to the initial CFD or Ansys Mechanical simulation, whereby the data is automatically transferred and mapped to the other system. In a two-way coupling simulation, the fluid and structural simulations are set up and solved concurrently, with data transferred between two solvers to achieve robust and accurate results.

    Customization and Scripting

The most expedient and straightforward method for adapting your simulation workflows. The Ansys Mechanical software allows users to customize repetitive tasks or specific workflows for automation and sharing with other users.

The incorporation of journaling and scripting capabilities facilitates the expeditious development and straightforward education of novel scripts.
