Abaqus is a complete Abaqus environment that provides an interface for creating, monitoring, and evaluating results from Abaqus/Standard and Abaqus/Explicit simulations. Abaqus/CAE is further divided into modules, where each module defines the aspect of the modelling process like defining the geometry, defining material properties, and generating a mesh.

ABAQUS - Simulation Analysis Software

CAE is a common graphical user interface that is used for modelling, solving, and post-processing a finite element problem.

The steps involved in the construction of a model are explained below-

ABAQUS Solver
ABAQUS Standard is an implicit solver used to solve nonlinear problems.
ABAQUS Explicit used for solving dynamics/wave propagation problems.

Part Module

Part Module Is the first step towards creating a model as parts are the building blocks of an Abaqus/CAE model. Part can be created in the following ways: Create the part using the tools available in the Part module. Import the part from a file stored in a third-party format. Import the part (mesh) from an output database. Import a meshed part from an input file.

You use the Part module to create, edit, and manage the parts in the current model. The Part module allows you to do the following:

Property Module

You can define the properties of a part or part region by creating a section and assigning it to the part. In most of the cases, sections refer to the materials that you have created. A material definition specifies all the property data relevant to a material. You can specify a material definition by including a set of material behavior's, and you supply the property data with each material behavior you include. Each material that you create is assigned its name and it is independent of any particular section. Abaqus/CAE assigns the properties of a material to a region/section of a part when you assign a section referring to that material that you have created to the region.

Assembly

You can use the Assembly module to create and assemble the assembly. A model contains one main assembly, which is composed of instances of different parts from the model as well as instances of other models. An instance maintains its association with the original part/model. If the geometry of a part changes, Abaqus will automatically update all instances of the part and changes will be reflected in the model. You can’t edit the geometry of an instance directly. Your main model can contain many parts and model subassemblies, and a part or model can be instanced many times with the main model assembly; however, a model contains only one main assembly. Loads/boundary conditions are all applied to the complete assembly.

Even if your model consists of only a single part, you have to create an assembly that consists of just a single instance of that part. A part instance can be a representation of the original part. You can create either independent or dependent part instances. An independent instance is effectively a clone of the part. A dependent instance is only a pointer to the part or virtual topology. You cannot mesh a dependent instance.

Step

Within a model, you can define a sequence of one or more analysis steps. The step sequence provides a convenient way to capture changes in the loading and boundary conditions of the model, changes in the way parts of the model interact with each other and any other changes that may occur in the model during the analysis.

Interaction

Interactions are step-dependent objects, which means that when you define interactions, you must indicate in which steps of analysis they are active. The Set and Surface toolsets in the Interaction module allow you to define and name the model to which you would like interactions and constraints to be applied. Abaqus does not recognize the mechanical contact between different part instances of an assembly unless the contact is specified in the Interaction module.

Load

Load is an independent module as Abaqus cannot apply load automatically; you have to select the load type and position on which load is to be applied. You can apply load to any node/Surface. You can use the Load module to define and manage the following prescribed conditions:

Loads
Boundary conditions

You can apply different types of loading

Concentrated force
Moment
General and shear surface traction
General shell edge load
Inertia relief
Current density

Boundary Conditions

Boundary Conditions is also an important module to check the specific point interaction. As Abaqus cannot apply real-life constraints in the model. So you have to manually specify the predefined condition to be applied to a model to make analysis more effective and accurate

Mesh

The Mesh module allows you to generate meshes on parts and assemblies created within Abaqus. Various levels of automation and control are available so that you can create a mesh that meets the requirements of the analysis model. As with creating the parts and assemblies, the process of assigning mesh attributes to the model such as seeds, mesh techniques, and element types is feature-based.

The Mesh module provides the following features:

Tools for prescribing mesh density and global levels.
Model coloring indicates the meshing technique is successful and assigned to each region in the model.
A variety of mesh controls, such as:
- Element shape
- Meshing technique
- Meshing algorithm
- Adaptive remeshing rule

Optimization

Optimization Is a process that generates results and analysis. You must combine the optimization results into an individual output file to view the results of the optimization in the Visualization module (Dassault).
