Abaqus Plugins (Add-ons) for Abaqus Users – Part I

Abaqus finite element software has several capabilities. Sometimes users need to customize features by writing Fortran user subroutines or Python scripting as needed to solve the problem. Some are commercial and some are not yet commercial. In this article, I have listed 14 handy Abaqus plugins that are used in the pre-processing and post-processing stages and I worked with them.

Abaqus plugins can:

• Speed up modeling and preprocessing tasks
• Automate repetitive simulations using scripting
• Enable complex analyses like contact, FSI, and optimization
• Integrate with other software for joint simulations
• Provide visualization of simulation results

Therefore, if you work in a specific field of FEA simulation, be sure to prepare them. Wait for the second part of this post.

Essentially Abaqus Plugins

Stress-strain Curve Calculator Abaqus Plugin

Stress-strain Curve Calculator abaqus plugin API 579 FFS

The Stress-Strain Curve Calculator Abaqus plugin allows an Abaqus/CAE user to generate a stress-strain hardening curve applicable to the design and fitness-for-service assessments (FFS- level 3) of pressure vessels and piping equipment.  Plasticity hardening curves are often needed in the design and analysis of metallic components and structures.  Elastic perfectly plastic and elastic bi-linear plastic models may not be adequate for all applications.  This is particularly applicable when utilizing Design-by-Analysis methods described in ASME Section VIII Div. 2 documents for the design of pressure vessels and piping components or utilizing the ASME/API 579 Fitness-for-Service (FFS) document for assessing a pressurized component with a flaw.

Calibrate Nitinol Material Behavior Abaqus Plugin

calibrate nitinol material behavior abaqus plugin for material calibration

Calibrate Nitinol Material Behavior Abaqus Plugin is used for calibrating the superelastic & the superelastic-plastic behaviors of Nitinol for Abaqus/Standard or Abaqus/Explicit analyses.

The plugin provides a user-friendly interface to create Nitinol material parameters based on uniaxial tension test data. Necessary keywords and data lines will be generated automatically based on a few characteristic points selected from the test data. The material will be renamed according to the required naming convention for Nitinol and can be directly used inside Abaqus/CAE. In addition, Calibrate Nitinol Material Behavior plugin offers an option to evaluate the material definition with a uniaxial 3D one-element model. If you select this option, the plugin submits the analysis and plots the results with the original test data for comparison. You can iterate the above process by editing the points picked on the test data until the desired material behavior is achieved.

Creep Evaluation Abaqus Plugin

Creep Evaluation abaqus plugin utility for material calibration

The creep Evaluation Abaqus plugin utility was very effective for me. Before that, I had to use a lot of code in MATLAB and Excel to calibrate and evaluate the creep constants.

It is similar to the Hyperelastic material evaluation tool within Abaqus/CAE – but for creep properties. The user must supply experimental data from a uniaxial creep test.

The Creep Evaluation plugin uses a least-squares technique to evaluate the constants that are appropriate for both the time and strain-hardening forms of the creep relationship.

​​​​​​​This plugin will allow you to evaluate the material constants for either the time or strain power-law creep, model. The user supplies material data (time, against creep strain) taken for different stresses.

MatLib Abaqus Material Library / Plugin

matlib abaqus plugin - abaqus material database

Having a library of materials with ready-made parameters helps accelerate and increase the accuracy of modeling and analysis in Abaqus. MatLib is a powerful library with more than 1400 materials in 22 groups such as composites, polymers, metals, etc. that have different models of materials such as elastic, plastic, damage, temperature and strain rate dependent, and many other specifications. The library is available in 3 units SI, SI (mm) metric, & Imperial. The plugin was developed by the Banu Musa simulation company.

Micromechanics Abaqus Plugin

Wound Composite Modeler Abaqus Plugin

wound composite modeler abaqus plugin for COPV design

The Wound Composite Modeler (WCM) plugin allows the user to define all the necessary information to create, analyze, and post-process a finite element model of a wound composite pressure vessel. The WCM plugin applies a symmetry boundary condition at the mid-length point of the cylinder so that a half-symmetric model of the complete pressure vessel is created. If a given tank design has different end dome geometries, it can be analyzed by creating two separate models, one for each end of the vessel.

Analysis Approach

  • Dome and Cylinder Geometry Definition
  • Winding Layout Specification
  • Mesh and Section Creation
  • Loading
  • Output
  • Results

Including 5 workshops:

  • Workshop 1: Generating Axisymmetric COPV Models
  • Workshop 2: Generating 3D COPV Models
  • Workshop 3: Autofrettage Analysis
  • Workshop 4: Design
  • Workshop 5: Buckling and Debonding

Johnson-Cook Constants Abaqus Plugin

johnson cook constants abaqus plugin for material calibration

In Abaqus, there is a material model named Johnson-Cook. Johnson-Cook constants Abaqus plugin have been developed to evaluate its parameters. In this way, the parameters related to this material model can be easily found without referring to handbooks and papers.

Autodesk Helius PFA Abaqus Plugin

autodesk helius pfa abaqus plugin for frp composite fatigue analysis

Autodesk Helius PFA Abaqus plugin is a good plugin to simulate the damage of composite materials that I have good experience with. With the Helius PFA Abaqus plugin, it is possible to predict the dynamic failure and fatigue of composite materials, which is a non-motivational feature and can be used in addition to Abaqus in Ansys.

Bolt Studio Abaqus Plugin

bolt studio abaqus plugin

The Bolt Studio Abaqus plugin provides the user with a streamlined method for defining bolts, nuts, and washers and placing them into an existing Abaqus/CAE model. Users can control the default set of bolts that are displayed in the interface via a simple Python-based configuration file.

The bolts, nuts, and washers, where applicable, are generated parametrically within Abaqus/CAE and meshed automatically using a hexahedral mesh.

The mesh size is determined automatically based on the dimensions of the bolt (the user can re-mesh if required, the parts using the native meshing tools within Abaqus/CAE). The bolt is automatically partitioned and the user-specified pre-loading is applied.

Focused Mesh Contour Integral Crack Builder Abaqus Plugin

focused mesh contour crack builder abaqus plugin

For many years Abaqus/Standard has included the ability to assess quasi-static, stationary crack fracture mechanics problems using contour integrals. While an XFEM-based contour integral method has been added in recent years, the conventional approach involves constructing a specific “focused” mesh configuration at the tip of the presumed crack.  The Focused Mesh Contour Integral (FMCI) Crack Builder is an Abaqus plugin to automatically create focused mesh partitions, meshes, and contour integrals (including q-vectors) for conventional focused mesh contour integral fracture analysis

ROMAC bearing Abaqus Plugin

romac bearing abaqus plugin

ROMAC bearing code is one of the popular bearing codes used in the Rotordynamics field. It is developed by ROMAC Laboratory at the University of Virginia. With the ROMAC bearing Abaqus plugin you can perform rotor dynamics analyses easily with the bearing property information given by the ROMAC bearing code.

ROMAC bearing Abaqus plugin is useful to import the bearing properties from the ROMAC bearing code THPAD, THBRG, and MAXBRG and write those in Abaqus input format. Using the Abaqus plugin, you can also manually fill out the bearing properties and write them in Abaqus input format.

The Abaqus input file .inp (which contains the properties of the connector element of the bearing with a given bearing name), is created using the plug-in. You can use the created properties in the proper connector element in your model.

Three separate plug-ins allow for three different approaches to entering the bearing properties:

  1. Calculate Coefficients
  2. Manual Input
  3. Read from File

The Calculate Coefficients plug-in directly runs the ROMAC bearing software (THPAD or THBRG) and writes the bearing properties in an Abaqus input file. The output file name is set as *.inp using the bearing name which is assigned in the plug-in by default, after importing the bearing results. You must have the ROMAC bearing software (THPAD or THBRG).

The Manual Input plug-in allows you to enter the bearing properties manually and write them to an Abaqus input file.

The Read from File plug-in reads the ROMAC bearing output file and writes the bearing properties in an Abaqus input file.


  1. By default, ROMAC uses English units. The plug-in can convert it to SI units.
  2. For uncoupled property, there is no version limitation. But for coupled property, only Abaqus 6.12 and later is available.

Units Converter Abaqus Plugin

units converter abaqus plugin

The Units Converter Abaqus plugin is a handy tool for converting common units within ABAQUS/CAE. It is developed by James Lockley in 2005. Units are converted from one measurement system to another system. You can also develop your unit system. It is very useful.

Abaqus Welding Interface Plugin

 abaqus welding interface plugin AWI plugin

The Abaqus Welding Interface (AWI) Plugin streamlines the generation of two and three-dimensional welding simulations from within Abaqus/CAE. This application provides a model-tree-based approach to defining all aspects of the weld model such as weld beads, weld passes, film loads, and radiation.

Honeycomb Modeler Abaqus Plugin

Honeycomb modeler abaqus plugin

The Honeycomb Modeler Abaqus plugin can be used with any model included in an Abaqus/CAE database. It automatically creates honeycomb structure models. The honeycomb structure is described in the plug-in by its:

  1. material;
  2. unit cell geometry; and
  3. dimensions.

Any material that has been created in the model can be accessed from within the plug-in. In addition, new material can be conveniently created from within the plug-in by calling the material editor.

Working with the plugin is very simple and enjoyable.  A lot of time spent on the geometric modeling of a honeycomb is minimized with this plugin. I recommend any Abaqus user have the Honeycomb Modeler plug-in for simulation.
