It seems like the answer options are missing from your query. Abaqus, a powerful suite of finite element analysis (FEA) software, is primarily written in a combination of programming languages, reflecting its complex and multifaceted nature.
Programming languages used
- Core Solvers: The underlying solvers, such as Abaqus/Standard and Abaqus/Explicit, are developed using high-performance compiled languages like C++ and Fortran. This choice is driven by the need for computational efficiency and speed when performing complex numerical calculations in finite element analysis.
- Scripting and Customization: Abaqus extensively utilizes Python as its standard scripting language.
- Abaqus Scripting Interface (ASI): Python serves as the foundation for the ASI, which provides an API (Application Programming Interface) for interacting with Abaqus models and data.
- Automation: Python scripts allow users to automate repetitive tasks, create and modify models, submit analysis jobs, and extract results from output databases (.odb files).
- Abaqus/CAE: Python is the language used by the Abaqus/CAE GUI (Graphical User Interface) to generate commands that are sent to the Abaqus kernel for processing, according to Read the Docs.
- User Subroutines: While Fortran has been the traditional language for writing user-defined subroutines (UMAT, UEL, etc.) in Abaqus, it's also possible to develop these subroutines in C or C++.
- GUI Development: Abaqus/CAE uses the fox-toolkit for GUI development.
