What is ANSYS mechanical enterprise?

ANSYS mechanical enterprise is the flagship mechanical engineering software that uses the power of FEA (Finite Element Analysis) for the structural analysis of complex geometries and products. It covers an enormous variety of products and comes packed with everything you need starting from the geometry preparation to complete product optimization and all the things in between. With the power of ANSYS mechanical enterprise, the users can model significantly advanced and complex environmental loadings and materials along with industry-specific requirements in areas such as layered composite materials and offshore hydrodynamics. 

ANSYS mechanical enterprise capabilities

ANSYS mechanical enterprise capabilities include many different and advanced solver models and capabilities that are much advanced than the basic versions of ANSYS mechanical suites.

Non-linear applications

Mechanical engineering software with non-linear analysis techniques includes the simulation of geometric, the simulation of contact, and material nonlinearities. ANSYS mechanical enterprise allows the engineers and researchers to study in-depth the effects of all these non-linear applications either in isolation or unison. 

The interfaces between the simulation of the parts through the contact parts can account for pressure, heating, cohesion, and friction to increase the accuracy of the parts and joints as how they would behave in real-life scenarios. 

Advanced material models for metals, composites, hyper elastics, and geomechanics, combined with the user-defined materials, provides a complete solution for non-linear analysis in great depth. Many different materials can easily be incorporated into the simulations via the vast material model library that comes in the suite. 

ANSYS mechanical suite also allows the users to compute their models that have very large deformations easily. By using nonlinear adaptive meshing, the product engineers can compute their products quite easily in places where the traditional approach may struggle.

Dynamics

ANSYS Mechanical enterprise includes a full range of capabilities for the dynamic FEA simulation. The transient simulations (let it be explicit or implicit), linear or rotor capability all combine to provide the user with a complete solution for the simulations in the frequency and time domains. This is done within a unified interface so that the learning time, along with the set-up time can be reduced significantly. 

The explicit solutions make it possible for the solver to simulate extreme deformation and high-speed impacts for objects which includes drops from high heights, impacts with a hard surface, and forming simulations.

With advanced ANSYS mechanical enterprise solvers and capabilities, the solver can compute faster than ever before and perform simulations for modal, spectrum response, harmonics or random vibrations. Along with these capabilities, the solver can also compute and solve complex geometries for rotating machinery for rotor dynamics analysis. 

Advanced ANSYS SpaceClaim

ANSYS SpaceClaim, which itself is an advanced direct modeling tool has even better capabilities in the ANSYS Mechanical enterprise. SpaceClaim can handle all the direct modeling requirements of your design from scratch and can help you clean and repair dirty geometries for simulation preparations. All the traditional CAD tools fall short in front of the advanced solvers of the ANSYS SpaceClaim.
In ANSYS Mechanical Enterprise, SpaceClaim also allows the CAD files from many systems to be directly read in, and files from the ECAD tools to be used to construct the electronic models. Faceted STL data can also be easily made in the software which is ready for analysis and especially useful in importing scan data or carry out reverse engineering. Advanced meshing tools are also available which can be used to create high-quality hex meshes even on the highly complex geometries. 

Composites

Composites are widely known to impart the material strength while greatly reducing the weight of the product or component, thus resulting in a substantial increase in energy efficiency. ANSYS Mechanical enterprise has both the modeling and material capabilities to model complex composites with confidence. Layered composites structures can be modeled the same way as they are ‘actually’ manufactured. Layers are added to the model, and the orientation, draping and shear forces encountered by the fabric are captured. If required by the user, the model can then be turned into a 3-D solid model. 

The post-processing in the composites can be easily used to analyze the failure criteria for the complete model with just one step and helps better understand the failure of mechanisms, along with the layer and element of the model in which the failure is likely to take place. 

With the aid of ANSYS Mechanical suite, the layered composites modeling either in solids or in shells, without or with core materials, can be carried out with confidence. Engineers can also combine the composite parts with other non-composite parts in one simulation model and build a complete assembly model for the real engineering insights. 

What’s new in ANSYS Mechanical Enterprise?

The ANSYS flagship mechanical engineering software has several new features added to it in the current iteration. The new features and capabilities of ANSYS mechanical enterprise are as follows;

Materials

ANSYS Mechanical enterprise has a whole range of materials models covering everything from shape memory allows, soils, concrete, hyper elastics, plastics, and metallic structures. The users can also add their own material models if needed. 

Material designers can easily create RVE’s  (Representative Volume Elements) based around the fiber, lattice, weave, or user-created geometries to enable the multiscale modeling of complex material structures.

Dynamics

ANSYS Mechanical Enterprise covers all your needs for dynamic analysis including linear dynamics, modal, harmonics, random vibrations, spectrum response with pre-stress, and state of the art solver options for rapid solutions. Mechanical enterprise solvers in the transient domain enable you to develop time-dependent scenarios. The rigid body dynamics capabilities of the enterprise let you solve the complex mechanisms rapidly. It also allows you to include the CMS (Component Mode Synthesis) parts to add flexibility to models while accelerating the simulations and reducing the overall working time. 

Acoustic simulations can also be carried out to better understand the vibroacoustic behavior of different systems, with or without the structural pre-loadings. The users can also create accurate waterfall plots to understand the results over varying frequencies better. 

Brake Squeal Analysis

Brake discs in huge moving bodies such that in aircraft or trucks, develops and sustains friction-induced oscillations. These friction-induced oscillations are often referred to as brake squeal, a challenging issue for researchers and engineers across the globe.

With the aid of eigensolvers of ANSYS Mechanical enterprise, the user can easily analyze squealing by identifying the unstable modes. Three different approaches of ANSYS mechanical allows the users to predict the behavior of the brake discs accurately and with high computing speed. This includes various levels of pre-stress scenarios that can be applied to the model. Lufthansa Technik AG is one of many renowned companies that leverages the power and capacity of ANSYS mechanical enterprise for the benefit of their products. One of the areas where Lufthansa applies this software is the prediction of wear and tear of their aircraft components, especially the disc brake, the flaps, and the doors hinges. 

Where does ANSYS Mechanical enterprise lie in the ANSYS ecosystem?

ANSYS mechanical enterprise is the most advanced and complex products by ANSYS Inc. It incorporates the categories of solvers ranging from structural analysis to electromagnetic to fluid simulations. All the solvers in this suite comprise of the advanced simulation capabilities and allow the users to discover and research their products with even more depth as never before.
