Learn About the Many Innovative Features of ANSYS 18

I’m excited and honored to share with you the innovations in the latest release of our suite of simulation solutions, ANSYS 18, on behalf of over a thousand R&D professionals at ANSYS. The driving force for these innovations is the spread of simulation to all areas of engineering practice, a trend we call “pervasive engineering simulation.

This trend is enabling engineers to explore the design parameter space earlier in the product lifecycle (digital exploration), test thousands of detailed designs rapidly and efficiently (digital prototyping), and monitor and optimize their product’s operation after it has been deployed (using digital twins).

To make pervasive engineering simulation as easy as possible for all engineers, we’ve added a lot of new features to each product family, as you can see below. For more information on ANSYS 18, including demo videos, webcasts, application briefs and technical papers, see our ANSYS 18 web pages.

It includes full versions of all ANSYS CFD solvers, plus special solutions for combustion, icing and material processing, as well as technology for geometry editing and clean-up, meshing, optimization and system simulation. This single product addresses the broadest array of fluid simulation applications with ANSYS’ gold standard accuracy. Check out this CFD Product Comparison chart to see the full breadth of this product. The ANSYS fluids suite also offers new breakthrough harmonic analysis for accurate and reliable turbomachinery analysis 100 times faster than before, as well as meshing advancements that accelerate simulation for assemblies with moving parts.

Harmonic Analysis delivers the same accuracy as a full wheel solution while speeding the simulation by up to 100x.


In the structures suite, ANSYS 18 has innovative tools and technologies to analyze complex materials, and to optimize designs and shapes for new manufacturing methodologies. New parallel topology optimization technology makes lightweighting of structures to meet design and performance needs easy. With our new spectral fatigue capability, you can accurately model and predict the structural integrity of electronic components. Using hierarchical submodeling, you can predict thermal stress and warping from the package and printed circuit board level, up to complete electronic systems using CAD and ECAD representations.

ANSYS Mechanical has new built-in topology optimization to easily determine where material can be removed for lightweighting of components.


The electromagnetics portfolio addresses the megatrends of mobile communications, energy efficiency and automation. ANSYS 18 delivers a faster, more robust design process that helps you to perform detailed electronics simulation earlier in the design cycle. The antenna and wireless design suite features a new streamlined workflow with an enhanced antenna design kit, broadband adaptive meshing and advanced computational capability to solve large-scale electromagnetic simulations for autonomous vehicle development and other advanced communication systems.

The chip-package-system workflow features a highly advanced 3-D layout assembly capability that supports multiple IC packages, printed circuit boards and connectors in a single environment. Engineers can now perform transient circuit-based simulation, system-level verification and comprehensive cooling analysis from a single design. With these enhancements, you can perform 3-D electromagnetic simulation as easily as basic circuit analysis, but with results that are orders of magnitude more accurate. Engineers in the industrial machinery and power electronics sectors can now analyze noise-vibration in electric motors and transformers, which is essential to developing quiet, efficient machines. The low-frequency solution also includes powerful new capability to simulate electromagnetic and thermal effects in planar magnetic components, critical for designing lower profile consumer electronics and power transformers.
