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. 

Nonlinear simulation also takes into account contact and large deflection of parts moving around relative to each other, either with or without friction.

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.

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.

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.

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.

Ansys Composite PrepPost (ACP) is a dedicated tool for modeling composite layups and failure analysis. You can generate layered composite models for implicit and explicit structural, thermal and fluid simulations. 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. Beyond the modeling of composite structures, Ansys Composite Cure Simulation (ACCS) simulates the curing manufacturing process. It helps you to simulate the curing process of a part and predicts residual stresses and process- induced distortions.

These include SPARs, FPSOs, semi-submersibles, tension leg platforms, ships, renewable energy devices and breakwaters. Our product, 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.

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.

Journaling and scripting capabilities enable quick development and easy education of new scripts.
