It is the first software in China that has passed the certification of the Technical Committee for Pressure Vessel Standardization and has been promoted and used by 17 ministries of the State Council. Now there are many pressure vessel design units using ANSYS finite element analysis software for the design of pressure vessels.
ANSYS software is a large general finite element analysis software integrating structure, fluid, electromagnetic field, sound field and coupling field analysis. It is developed by ANSYS, one of the world’s largest FEA software companies, and can interface with most CAD software to realize the common grass and exchange of data, such as Pro/Engineer, UG, SolidWorks, NASTRAN, Alogor, CATTAJ-DEAS, AutoCAD, etc. It is one of the advanced CAE tools in modern product design. ANSYS finite element analysis software can perform analysis and calculation of the whole or parts of the equipment.
ANSYS software consists of three main parts: pre-processing module, analysis and calculation module and post-processing module.
The pre-processing module provides a powerful solid modeling and mesh partitioning tool that allows users to easily construct finite element models.
The analysis and calculation module includes structural analysis (linear analysis, nonlinear analysis and highly nonlinear analysis), fluid dynamics analysis, electromagnetic field analysis, acoustic field analysis, piezoelectric analysis and coupling analysis of multi-physical fields, which can simulate the interaction of various physical media and have the ability of sensitivity analysis and optimization analysis.
The post-processing module can display the calculation results as color contour display, gradient display, vector display, particle flow trace display, stereo slice display, transparent and semi-transparent display (you can see the inside of the structure) and other graphics, and can also display or output the calculation results in the form of graphs and curves.

ABAQUS is a powerful finite element software for engineering simulation, and its problem solving range from relatively simple linear analysis to many complex nonlinear problems. It also has a library of material models of various types to simulate the properties of typical engineering materials, including metals, rubber, polymers, composites, reinforced concrete, compressible superelastic foams, and geological materials such as soil and rock. As a general-purpose simulation tool, ABAQUS can solve a large number of structural (stress/displacement) problems in addition to many other engineering fields, such as heat transfer, mass diffusion, thermoelectric coupling analysis, acoustic analysis, geotechnical analysis (fluid penetration/stress coupling analysis) and piezoelectric dielectric analysis.
ABAQUS provides users with a wide range of capabilities and is very easy to use. A large number of complex problems can be easily simulated by different combinations of option blocks. For example, complex multi-component problems are simulated by combining option blocks that define the geometry of each component with the corresponding material properties option block. In most simulations, even for highly nonlinear problems, the user only needs to provide some engineering data, such as the geometry of the structure, material properties, boundary conditions, and loading conditions. In a nonlinear analysis, ABAQUS can automatically select the appropriate load increments and convergence limits. It is not only possible to select the appropriate parameters, but also to continuously adjust them to ensure that the exact solution is efficiently obtained during the analysis. The user is able to control the numerical calculation results by defining the parameters exactly.

ABAQUS has two main solver modules-ABAQUS/Standard and ABAQUS/Explicit. ABAQUS also includes a graphical user interface that fully supports the solver, the human-computer interaction pre and post-processing module-ABAQUS/CAE. ABAQUS also provides specialized modules to solve specific problems.
ABAQUS is widely regarded as the most powerful finite element software for analyzing complex structural mechanics systems of solids, especially for navigating very large and complex problems and for simulating highly nonlinear problems.
