“…Usually, the standard functionality of such commercial software can be extended by some form of custom code, such as user subroutines or macros. User subroutines allow to modify and extend the default behavior of numerical engines, while macros can be used to automatically prepare input data and read output data from result databases [10].…”

The implementation of a dedicated communication mechanism between micro-and macroscale models of the fully coupled multiscale numerical approach is the topic of the paper. The presented solution is based on the System V IPC message queue that is part of modern Linux-based operating systems. Developed and implemented approach is validated with a selected case study of a 3D compression test with the microscale model based on an implicit Johnson-Cook model, which is solved as a separate external process. The communication mechanism can be the basis of the efficient fully coupled FE 2 model.

This data article presents the source codes and obtained simulation data for running numerical fracture simulation in the commercial finite element package, ABAQUS. The computational models implemented through these source codes pertain to the conventional and localizing gradient damage method which are used for the modelling of the fracture phenomena in the components and structures. For a detailed description refer to “A comparative study and ABAQUS Implementation of Conventional and Localizing Gradient Enhanced Damage Models [1]”. The implementation is carried out using a feature in the ABAQUS software called the user defined subroutines. The subroutines are a set of coded files which are used to implement any newly developed computational models depicting actual physical phenomena which are not already available in any commercial software. The user subroutines used in this implementations are UEL and UMAT. The present implementation is very user friendly in the sense that the user needs to just type a couple of commands in the ABAQUS command application to run the simulations. Moreover, the ability of the ABAQUS to run large scale simulations using a very sparse amount of computational resources enables researchers and engineers with limited resources to take advantage of a very advanced computational fracture simulation technique.
