Structural Mechanics Simulation with FEM

Perform acoustic simulations to understand the vibroacoustic behavior of systems, with or without structural preload. Including preload enhances fidelity and allows for the simulation of self-weighted bolted assemblies, or even squealing brakes.

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

It can simulate everything, from bonded contact that treats joints between parts as if they were glued or welded, to contact interfaces that allow parts to separate and assemble with or without friction effects. Proper contact simulation enables the modeling of load path changes as parts deform and confidently predicts the behavior of assemblies in the real world.

Any model in Ansys Mechanical can be used to drive parametric optimization. Shape and topology optimization capabilities allow for the creation of efficient geometries, which can be transferred to CAD for production or other simulation work. Additive manufacturing, weight reduction, and robust design are excellent use cases for this technology.

Ansys Mechanical allows you to read power losses or temperatures calculated from other analysis systems or files, meaning that CFD or electromagnetic simulations can serve as a starting point for thermal analysis. It is also possible to account for fluid flow in pipes and heat generated by friction between parts. All these capabilities enable 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 material property data you need, eliminating the time spent searching for data and reducing input errors. Material Designer can easily create representative volume elements (RVEs) based on lattice, fiber, weave geometries, or user-defined designs to facilitate multi-scale modeling of complex material structures.

Ansys Mechanical allows for the modeling of laminated composites through its connection with Ansys PrepPost (ACP), and short fiber composites through integration with upstream manufacturing simulation tools and material behavior data obtained from Material Designer, Ansys’ tool for multi-scale homogenization of material microstructures.

You can generate composite models for implicit and explicit structural, thermal, and fluid simulations. Ansys Composite PrepPost (ACP) is the Ansys tool dedicated to modeling composite assemblies and analyzing failures. ACP offers efficient first-order solid element modeling capabilities and a platform with extensive options for exchanging model information. It supports the IAO composite HDF5 file format, which is vendor-independent, for communication with third-party tools, many of which are dedicated to and linked to composite manufacturing. Beyond composite structure modeling, Ansys Composite Cure Simulation (ACCS) simulates the curing process during manufacturing. ACCS is an extension of Ansys Mechanical that helps you simulate the curing process of a part and predict the residual stresses and distortions induced by the process to perform compensation analyses.

This includes SPARs, FPSOs, semi-submersibles, jack-up rigs, ships, renewable energy devices, and breakwaters. Our product, Ansys Aqwa, has been widely used in the oil and gas, renewable energy, and general engineering sectors to model the installation and operation of equipment in open seas as well as in ports or sheltered locations.

Unidirectional coupling solves the initial CFD or Ansys Mechanical simulation and automatically transfers the data to the other system. In a bidirectional coupling simulation, the fluid and structural simulations are set up and solved simultaneously, with data automatically transferred between the two solvers to achieve robust and accurate results.

The journaling and scripting features enable rapid development and easy training of new scripts.
