If you’ve ever seen a rocket launch, flown on an airplane, driven a car, used a computer, touched a mobile device, crossed a bridge, or put on wearable technology, chances are you’ve used a product where ANSYS software played a critical role in its creation. ANSYS is the global leader in engineering simulation. We help the world’s most innovative companies deliver radically better products to their customers. By offering the best and broadest portfolio of engineering simulation software, we help them solve the most complex design challenges and engineer products limited only by imagination.

The flagship tool for Finite Element Analysis: -ANSYS Mechanical Enterprise is the flagship mechanical engineering software solution that uses finite element analysis (FEA) for structural analysis using the ANSYS Mechanical interface. It covers an enormous range of applications and comes complete with everything you need from geometry preparation to optimization and all the steps in between. With Mechanical Enterprise you can model advanced materials, complex environmental loadings and industry-specific requirements in areas such as offshore hydrodynamics and layered composite materials.

Materials: –A whole range of material models covering everything from hyper elastics, shape memory alloys, soils, concrete, plastic and metallic structures can be accurately modeled; you can even add user-defined material models if needed.

Material Designer can easily create representative volume elements (RVE’s) based around lattice, fibre, weave or user-created geometries to facilitate multiscale modeling of complex material structures.

Dynamics: –Mechanical Enterprise can cover all of your needs for dynamic analysis, including — for linear dynamics — modal, harmonic, spectrum response and random vibration with pre-stress, and advanced solver options for rapid solutions. In the transient domain both implicit and explicit solvers enable you to model time dependent scenarios. The Rigid Body Dynamics capability lets you solve mechanisms rapidly. It also enables you to include Component Mode Synthesis (CMS) parts to add flexibility to models while still accelerating the simulation.

Acoustic simulations can be carried out to understand the vibrio-acoustic behaviour of systems, with or without structural pre-loading. You can also create waterfall plots to more conveniently understand results over varying frequencies.

Additional value: -Mechanical Enterprise has tools such as ANSYS ACT to customize your workflow, add functionality and accelerate your simulation process, and ANSYS Design Xplorer with built in optimization technology to get to the best answer in the fastest time ever. The addition of ANSYS Space Claim means that preparing geometry (mid-surfacing, beam extraction and simplification) for analysis, building prototype models or manipulating geometry during design changes is intuitive and rapid.
