Fortran for Abaqus Subroutine

The Fortran language was designed in the 1950s at IBM by a team led by John Backus.  Fortran is one of the most popular programming languages in numerical calculations. This language is very efficient, simple, and fast for solving finite element problems. These features make it the first choice for high-performance computing (HPC) by engineers and scientists.

Numerical simulation engineers, both CFD and FEM, are familiar with this program and its capabilities. Since ancient times, Fortran has been used in many numerical simulation software, and even now it plays a significant role in the development of software such as Abaqus.

In Abaqus, this programming language is available to engineers, students, and researchers along with C and C# for developing numerical codes known as user subroutines. Various tasks can be done with the help of subroutines. For example, you can develop new material models, try different loadings and even produce new elements! These are a small part of the capabilities that are provided to users with the help of subroutine. The key to entering this field is learning Fortran for Abaqus Subroutine. In this course, I will try to provide you with the experiences gained from 10 years of writing subroutines.

Why & when to use user subroutines?

• When Standard Abaqus’ built-in capabilities are limited, restrictive, or insufficient
• Go away from black-box modeling
• Achieve more accurate material models from experimental data
• Adapt Abaqus to a particular analysis requirement
• Straightforward for others to use your code
• When the features and options in the Abaqus do not meet the user’s needs,
