Introduction

If you have ever driven a car, flown aboard an aircraft, used any electronic gadget, trekked over mountains using your gear, crossed a bridge, or have ever played football, the chances are that you have used a product where ANSYS played an important role in its designing and creation.

Overview

ANSYS is an internationally recognized global leader in all sorts of engineering simulations and has helped many companies across the globe to come up with radically better products for their valued customers. ANSYS has helped solve complicated design challenges and engineer products that are limited only by imagination.

As time goes on and as the lines between the physical and the modern world blur, no one can deny the fact that products are becoming increasingly complex to manufacture. Modern technological trends such as the development of autonomous vehicles, implementation of 5G technologies and rapid manufacturing techniques such as 3D printing have all radically changed the product development methodology – making it more difficult for companies to keep pace with ever-tightening timelines and budgets. ANSYS 19 is the solution to all these engineering needs. It empowers engineers and product designers to tame complexity and dramatically improve their efficiency for higher productivity.  

From a revolutionary user experience in ANSYS static structural to the super-accurate fluid simulations in ANSYS CFX, and groundbreaking capabilities in ANSYS additive print, ANSYS 2019 has maximized the user’s productivity across all major industries. According to general manager and the vice president for ANSYS software, ANSYS 19 is the next generation of the pervasive engineering simulation and a Multi-physics solution to engineers at all levels (ANSYS Inc, 2019). Engineers and designers can now make important design decisions confidently, push the design limits further and reduce the production time – without sacrificing quality.

Each year ANSYS Inc launches new iterations to its’ software to cope with the market requirements as well as to improve the overall simulation performance. The latest iteration to the software is the ANSYS 19. ANSYS 19 covers a wide array of different simulation capabilities packed into one unified software. Here are the highlights of the latest release.

New User Interface

In the latest version of ANSYS, a reworked ANSYS Fluent user interface is being implemented over the top of its already industry proven workflow process. The new ANSYS Fluent user interface allows the design engineers to benefit from a single workflow solution as opposed to multiple workflows in the previous versions of the software. A single workflow in ANSYS 19 improves the overall speed as well as lowers the complexity in each step. The new Fluent interface in ANSYS 19 also streamlines the workflow of generating the mesh on imported CAD and allows for the users to iterate the mesh faster with significantly less training.

The new user interface for the Fluent in ANSYS 19 has user-focused enhancements that enable better problem-solving than ever before. New task-based workflows now smoothly work with the parallel processing to greatly reduce the solving time for meshing and further simulations. According to several reports, Mosaic-enabled Poly-Hexcore meshing can be done 10x times faster as compared to the older versions of ANSYS. This is a breakthrough in fluid simulation as it dramatically lowers the simulation time and ramps up product designing and production phase.

According to the R&D thermal research engineer at INDAR, Itsaso states that the Mosaic technology in the new ANSYS 19 allows for the meshing and simulating prepossessing of the thermals for their electric generators to be carried out in a matter of hours. Before this, it took a staggering week to complete this task. The new Mosaic-enabled technology also allows the users to reduce the mesh sizing by 30 percent  (Wilde, 2018).

Next-Gen for Electronics

For the prototyping and product testing in electronics, the new ANSYS 19 electronics and electromagnetic suite includes electromagnetic analysis, EMI scanner and NVH (Noise-Vibrating Harshness) capabilities. In ANSYS 19 Slwave, the electromagnetic analysis enables design engineers to precisely predict the time of failure for on-chip and advanced electronic packaging structures. The EMI scanner feature is an entirely new feature added to this latest iteration of ANSYS, and it allows to quickly identifies the location of potential electromagnetic interference on the custom printed circuits boards before the full elimination. This dramatically reduces potential errors in the circuit as well as speeds up the product manufacturing time. The NVH is a revolutionary workflow added to assist ANSYS 19 Maxwell®, ANSYS 19 mechanical, and the acoustic solver along with the ANSYS 19 Workbench. NVH workflow allows for the calculation of the electromagnetic noise of a machine due to the vibration caused by the electromagnetic forces. This allows for the creation of a complete noise profile of a machine within hours.

Introduction of a New Line of Product

ANSYS motion is a completely new line of product introduced with the ANSYS 19. It is termed as the most powerful Multibody Dynamics (MBD) solution available in the market today. Acquired from South Korea’s Virtual Motion Inc, MBD solvers offers a full suite of dynamic capabilities for both the flexible and rigid bodies. MBD solver in ANSYS 19 also features an extensive range of state-of-the-art application-based toolkits.

An Improved Structural Analysis

In the ANSYS 19, the structural analysis is now much more refined and efficient as compared to the previous structural solvers in the older versions of ANSYS. The new solver significantly improves on how the users solve assemblies with contact surfaces, enables the design engineers to make use of HPC (High-Performance Computing) as well as complete certain model analysis twice the speed than before.

More powerful than ever before, the new ANSYS 19 Mechanical solver can now compute highly complex and non-linear problems. The improved structural analysis also supplements engineering work with significant enhancements in fatigue crack growth and complex re-meshing to compute and solve highly deforming geometrics – a feat that was impossible to achieve in the older versions of ANSYS (Harris, 2018).

VR Experience for Autonomous Cars

Engineers can now experience their products and designs in an updated and refined system suite, ANSYS VRXPERIENCE®. It has two new integrated camera models which enable the users to test different algorithms in different driving conditions. This new feature is a big plus for the development of the autonomous vehicles as design engineers can now validate several of their automotive systems which were deemed too dangerous or expensive to be tested and replicated in physical tests. The VRXPERIENCE® also includes simulations of different scenarios with dynamic traffic and vehicle headlamps, HMI use cases and sensors. It also includes a SCADE plug-in interface which allows the design engineers to obtain rapid prototypes for ADAS control laws.

Expanded Physics Capabilities in 3D Design

In the new 3D design ANSYS 19 suite, there is added topology optimization to ANSYS® Discover Live. This new feature allows the engineers to carry out shape optimization in real-time and can take design optimization to a whole new level. Product manufactured via this new 3D design suite is better weight optimized with better strength. Designs which were sought to be impossible due to software limitation before are now a reality thanks to the updated and much more refined 3D design suite in ANSYS 19 (Harris, 2018).

Engineers in the defense and aerospace industries can also take advantage of the ANSYS 19 Discovery AIM®. This allows the engineers to add a random vibration solution to their product and see how it will behave under different vibrations. Alongside with all these new physics capabilities in ANSYS 19, a whole new design modeler is also implemented. The new design modeler, ANSYS SpaceClaim allows the creation and parameterizing of any concept model by including feature tracking and sketch constraints. As compared to older versions of ANSYS, SpaceClaim presents a better workspace to create both 2D and 3D designs and quickly sends it to meshing and further processing.
