Why It's Good to Understand What Your FE-Solver Is Doing
In this blog Christine Obbink-Huizer explores a customer support question problem discussing why it is good to understand what your FE solver is doing (and how you can become more knowledgeable as well!).

Simulating Crack Initiation and Propagation in Abaqus Using XFEM
In conventional FEM methods for crack propagation, the initial crack location needs to be predefined. This is not necessary when using eXtended Finite Element Method (XFEM). In this blog post I thought we would take a small dip into modelling fracture and failure in Abaqus using XFEM.

Abaqus Python Scripting: How Difficult Is It?
Scripting in Abaqus is a powerful way to reduce (wo)manhours and ensure a consistent method is used. Previously, we have given an example of postprocessing and tips on getting started. This blog discusses the kinds of problems that are easy or more challenging to script by using examples.

Meshing Complex Geometries in Abaqus
Geometry import and meshing is one of the key areas where we as FE analysts can spend a lot of time and effort. For meshing in particular, using hexahedral elements to mesh complex part can be difficult. In this blog we’d explore one way to obtain a hexahedral mesh for two relatively difficult parts.

Axisymmetric Analysis: Abstraction Shapes and FEM Reps
In Abaqus there is a direct relationship between geometry and the final meshed shape: if we want to defeature or do an axisymmetric analysis, the geometry needs to be modified. On the 3DEXPERIENCE platform, this is not the case. The geometry can remain unchanged. Discover more in the latest blog from Christine Obbink-Huizer.

Stent Analysis in Abaqus
Finite element analysis of stents is challenging. It typically involves small structures, large deformations, complex contact conditions and intricate material definitions. What can Abaqus offer for this type of analysis? In this blog we will find out.

Simulating Composite Materials in Abaqus: A Case Study on Bike Frames
In this blog I explore material choice for bike frames. The choice between aluminum, titanium, steel or carbon fiber is mainly related to the weight of the frame, but what about the loading? In this blog, I will simulate each frame, including the composite one, in Abaqus/Explicit.
