Introduction
ANSYS software is a large-scale general finite element analysis (FEA) software developed by ANSYS Company in the United States. It is the fastest-growing computer-aided engineering (CAE) software worldwide and can interface with most computer-aided design (CAD) software to achieve data sharing and exchange, such as Creo, NASTRAN, Algor, I-DEAS, AutoCAD, etc. It is a large-scale universal finite element analysis software that integrates structural, fluid, electric field, magnetic field, and sound field analysis. It has extensive applications in fields such as nuclear industry, railways, petrochemical industry, aerospace, mechanical manufacturing, energy, automotive transportation, national defense and military industry, electronics, civil engineering, shipbuilding, biomedicine, light industry, geology and mining, water conservancy, household appliances, etc. ANSYS is powerful, easy to operate, and has become the most popular finite element analysis software internationally, ranking first in FEA evaluations over the years. More than 100 science and engineering universities in China use ANSYS software for finite element analysis or as a standard teaching software.
Type of technology
There are many types of CAE techniques, including Finite Element Method (FEM), Boundary Element Method (BEM), Finite Difference Element Method (FDM), and so on. Each method has its own application field, and the application of finite element method is becoming increasingly widespread, which has been applied in structural mechanics, fluid mechanics, circuit science, electromagnetics, thermodynamics, acoustics, chemical and chemical reactions, etc.
The ANSYS finite element software package is a versatile finite element method computer design program that can be used to solve structural, fluid, electrical, electromagnetic, and collision problems. Therefore, it can be applied in the following industrial fields: aerospace, automotive industry, biomedicine, bridges, architecture, electronic products, heavy machinery, MEMS, sports equipment, etc.
The software mainly consists of three parts: pre processing module, analysis and calculation module, and post processing module.
The preprocessing module provides a powerful solid modeling and mesh generation tool, allowing users to easily construct finite element models;
The analysis and calculation module includes structural analysis (which can perform linear analysis, nonlinear analysis, and highly nonlinear analysis), fluid dynamics analysis, electromagnetic field analysis, sound field analysis, piezoelectric analysis, and coupling analysis of multiple physical fields. It can simulate the interaction of multiple physical media and has sensitivity analysis and optimization analysis capabilities;
The post-processing module can display the calculation results in graphical forms such as color contour display, gradient display, vector display, particle flow trace display, three-dimensional slice display, transparent and semi transparent display (visible inside the structure), and can also display or output the calculation results in charts, curves, or other forms.
The software provides over 100 types of units to simulate various structures and materials in engineering. This software comes in various versions and can run on various computer devices from personal computers to mainframes, such as PC, SGI, HP, SUN, DEC, IBM, CRAY, etc.
Development
ANSYS recently announced the launch of the latest version of its industry-leading engineering design simulation software, ANSYS 19.0. Its unique new features provide the best methods and more comprehensive solutions for guiding and optimizing product design. The engineering simulation software ANSYS 16.0 has made significant progress in various aspects such as structure, fluid, electromagnetic, multi physical field coupling simulation, and embedded simulation technology.
■Enable interconnection of electronic devices
The popularization of electronic device connection functions and the comprehensive development trend of the Internet of Things require higher standards for the reliability of hardware and software. The latest release of ANSYS 16.0 provides numerous functions to verify the reliability and performance of electronic devices, running through the entire product design process and covering all supply chains in the electronics industry. In ANSYS 16.0, the "ANSYS Electronics Desktop" was newly launched. In a highly integrated interface with a single window, electromagnetic field, circuit, and system analysis form a seamless working environment, ensuring the highest productivity and best practices in simulation in all application fields. Another important new feature in ANSYS 16.0 is the ability to create 3D components and integrate them into larger assemblies. By using this feature, it is easy to build a wireless communication system, which is particularly effective for increasingly complex system designs. Establish 3D components that can be directly simulated and store them in library files, making it easy to add these components to larger system designs without the need for any additional excitation, boundary conditions, and material properties settings, as all internal details are already included in the original design of the 3D components.
■Simulate various types of structural materials
Reducing weight while improving structural performance and design aesthetics is a challenge that every structural engineer faces. Thin materials and new materials are often used in structural design, and they can also introduce some difficulties for simulation. Thin metal sheets can provide the required performance while minimizing material and weight, making them a "traditional" material used in almost every industry. With ANSYS 16.0, engineers can accelerate the modeling speed of thin materials and quickly define the connection methods of various components in a complete assembly. ANSYS 16.0 provides efficient composite material design capabilities and practical tools to better understand simulation results.
■Simplify complex fluid dynamics engineering problems
Products are becoming increasingly complex, and at the same time, product performance and reliability requirements are constantly improving, which has prompted engineers to study more complex design and physical phenomena. ANSYS 16.0 not only simplifies the preprocessing workflow of complex geometric structures, but also speeds up to 40%. When engineers face multi-objective optimization design, ANSYS 16.0 achieves intelligent design optimization by utilizing adjoint optimization technology and achieving efficient multi-objective design optimization. The new version of ANSYS 16.0 not only simplifies complex design and optimization work, but also simplifies the simulation of complex physical phenomena. For ship and ocean engineering applications, engineers can use the new version to simulate complex ocean wave patterns. Rotating machinery design engineers (compressors, hydraulic rotating machinery, steam turbines, pumps, etc.) can use the Fourier transform method to efficiently obtain the interaction results between fixed and rotating rotating machinery components.
■Model-based system and embedded software development
Innovation based on systems and embedded software has shown significant growth in every industrial field. Major companies are facing numerous challenges in this development trend, especially how to design and develop these complex systems. ANSYS 16.0 provides multiple new features for system developers and their corresponding embedded software developers. For system engineers, ANSYS 16.0 has extended modeling capabilities, allowing them to define complex operating modes between the system and its subsystems. As systems become increasingly complex, their operations require a more comprehensive definition. System and software engineers can collaborate better in their collaborative projects, reducing research and development time and workload. ANSYS 16.0 has added a behavior graph modeling approach to address this requirement. In the aviation field, ANSYS 16.0 provides model based simulation methods for DO-330 requirements, which have been validated by DO-178C and have the highest level of safety requirements. This is the first tool for new certification requirements.
