User-subroutines in Abaqus Abaqus has a multitude of built-in features available for FE analyses, but it is possible for users to extend the software capabilities via user subroutines. User subroutines are written in Fortran and a Fortran compiler is needed to compile your software code. Since recently...

4RealSim is honoured and excited to work together with University of Palermo, Katholieke Universiteit Leuven, Ecole des Mines de Saint-Étienne, Xeltis, Capvidia, Leartiker, Graz University of Technology, and ISMETT in a newly formed European Consortium - SimInSitu - after receiving a grant from the EU...

What is DEM? The Discrete Element Method is a relatively simple method in which discrete spherical particles interact with each other and with other surfaces in an Abaqus/Explicit analysis. Granular or particulate matter can easily be simulated using DEM; each DEM particle represents a separate grain,...

Abaqus 2021 key features Abaqus/CAE (Enhanced Functionality) Modeling enhancements Directly import CATIA V5 files as parts on the Linux platform Specify multiple...

The International Committee on Aeronautical Fatigue and Structural Integrity (ICAF) was formed in 1951 in response to the growing concerns regarding fatigue problems in aircraft structures. The ICAF 2019 conference has been hosted in Krakow, Poland, and during the conference René Alderliesten gave the Dutch...

Hydrogen Embrittlement - A serious challenge for the industry Hydrogen embrittlement (also called hydrogen assisted cracking or hydrogen-induced cracking) describes the embrittling of metal after being exposed to hydrogen. Due to hydrogen embrittlement, structures can suffer from a loss of ductility, strength and/or toughness. This phenomenon...

This post provides an overview of the new key features of Abaqus 2020. Abaqus 2020 key features Abaqus/CAE (Enhanced Functionality) When partitioning cells by extrude/sweep of edges, the selected edges no longer need to be connected to each other You can now directly import Solidworks part...

There are various reasons why a Abaqus/Standard finite element simulation may not converge. This post provides a description of the most common convergence problems and an explanation what might be the cause of these occurrences. When convergence problems appear, one should review the output files...

Using Abaqus enabled Stadler Rail (a Swiss train building company) to confirm that the KISS railcar design successfully fulfilled all requirements of the European standards while optimizing weight and reducing product development times. This post is based on the Stadler Rail customer story written by Dassault...
