This is my last blog here and I want to take this opportunity to not talk about Abaqus or other technical stuff for once, but instead focus on something that is even more important to me: human connections.
Sometimes you have a mesh in Abaqus, and you don’t have the corresponding geometry. Abaqus offers tools to create geometry based on a mesh. Here I will discuss two options: using the mesh-to-geometry plug-in and using the built-in tools. I’ll explain the difference and when to choose which option.

Why it is good to understand what your FE solver is doing (and how you can become more knowledgeable as well!)
While doing support we get all kinds of questions. I want to share one with you in this blog, because it was insightful for me, and I hope it will be insightful for others as well.

This blog is on installing the Intel oneAPI Fortran compiler for use with Abaqus. It is an update of my previous blog, where some relevant information was only available in the comment section. This blog is intended to be used as a reference instead of the old blog.

Abaqus 2022 is available. In this blog I will highlight some of the modifications and provide a list of other improvements so you can check them out yourself if the topic is of interest to you.

Scripting in Abaqus is a powerful way to reduce working hours and ensure a consistent method is used. Previously, we have given an example of postprocessing and tips on getting started. Now I want to discuss what kinds of problems are easy or more challenging to script by using examples. Hopefully this will make it easier to find a suitable problem and get started scripting.

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. One or more abstraction shapes can be connected to the geometry, to represent simplified geometry. In this blog I will show this process for a bolt-and-nut assembly. We will have an axisymmetric model and 3D model based on the same geometry.
*An exception to this is the use of virtual topology. This allows small differences between mesh and geometry, by ignoring entities. This way you do not force the mesh to create element edges along all geometrical edges.

A fundamental question for each finite element problem is the type of solver to use: implicit or explicit? The solver type influences the set of equations that are solved, the availability of certain features, the run time and even whether a solution is obtained. It is therefore important. In this blog I’ll explain the difference between the two solvers available in Abaqus, their advantages and disadvantages, and when to choose which. I'll end with a simple example to illustrate the points made.
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.

In this blog we'll simulate a sheet metal forming process called deep drawing, with SIMULIA Abaqus Software. It can be challenging to design a deep drawing product and the tools to create it, because many potential issues are not observed until the first prototype is produced. Simulations can help determine whether a design suffices, without actually having to create costly tools or do time consuming tests. Multiple design iterations can easily be investigated.
