Optimization of hip implant done with SIMULIA Abaqus & SIMULIA Tosca

Posted by Christine Obbink-Huizer on Jan 28, 2020 9:45:00 AM

In the past, we have already given an example of optimizing a structure using Tosca. Now, I want to revisit this topic and focus specifically on geometry issues. I’ll explain how I obtained the geometry used for optimization, and also show how to get a 3D model of the optimized geometry, that can be used for further finite element analysis.

The example: a hip implant

Though we probably don’t always realize it, we use our hips a lot. After years of loading, they can become damaged and painful. In these cases, replacing the hip with an implant can be a solution. Here we are going to let Tosca design an optimized hip implant, as an example.

Join our online webinar: Abaqus 2020 - whats new

Posted by Dolf Broekaart on Jan 27, 2020 12:38:26 PM

Abaqus 2020 is out. In this webinar we’ll go through many of the modifications and new features, so you can determine where you can benefit from this release.

Have you ever wanted to do an interference fit in Abaqus/Explicit, import SolidWorks sldprt or sldasm files, define contact properties based on the materials of the underlying surfaces or simulate additive manufacturing? This, and more, is possible with Abaqus 2020.

Not possible for you to follow our online webinar? Read one of these blogs here and here.

Abaqus Hardening Laws on single element model

Posted by Nikolaos Mavrodontis on Jan 21, 2020 9:15:00 AM

In this blog post, we will be discussing about some of the most commonly used hardening laws that are available within Abaqus, and can be deployed whenever a metal’s plastic (inelastic) behavior and the nature of the applied load (monotonic, cyclic) becomes relevant in the modeling.

Introduction to Non-Linear Analysis - Free Abaqus Workshop - 31st Jan

Posted by Dolf Broekaart on Jan 13, 2020 5:01:14 PM

The “Introduction to Non-Linear Analysis Workshop” on the 31st of Jan, is a free event, held at our location in the Netherlands, for anyone who has some experience of simulation and FEA, but would like to look at extending the scope of the work they do. This workshop is an ideal way to understand what advanced simulation and SIMULIA Abaqus can offer, and find out how easy it actually is to perform a real world non-linear analysis.

Merry Christmas and a happy 2020!

Posted by Dolf Broekaart on Dec 20, 2019 2:55:32 PM

This year we have used SIMULIA XFlow CFD to determine whether Santa could fly without his beloved reindeers. (just don't ask me to mention all their names)

In order to determine whether Santa could fly like superman, we have created a virtual windtunnel study and used some assumptions. We have tried many iterations, but the best angle of attack seemed to be 20 degrees in order to create the most amount of lift.

Merry Christmas - Create your own Christmas tree in Abaqus

Posted by Christine Obbink-Huizer on Dec 17, 2019 9:30:00 AM

What if … you could let Abaqus draw a Christmas tree for you, according to your own specifications, and would then show it deforming under the load of the balls?

If wouldn’t change the world, but it would be kind of fun, wouldn’t it? At least that’s what I thought, which led to the Christmas tree plugin, that you can download from this page.

Abaqus 2020: What's new?

Posted by Christine Obbink-Huizer on Dec 9, 2019 5:41:40 PM

Abaqus 2020 is available. The installation is similar to that of Abaqus 2019, and we have a separate post to guide you through it. Click here for our blog Abaqus 2020: download an installation instructions.

Here I want to show a few of the modifications, and then provide a list of other improvements so you can check them out yourself if the topic is of interest to you.

Abaqus 2020: Download & Installation

Posted by Christine Obbink-Huizer on Dec 9, 2019 5:31:46 PM

Abaqus 2020 is now available. The download and installation is similar to that of Abaqus 2019.

As with Abaqus 2019, it is straight forward as long as the downloaded files are extracted to a common file structure and that the installation is done using (full) administrator rights, especially using Windows 10.

I’ll go through the process below. It includes print screens of most windows. Those that only require confirmation are left out for brevity. 

If you want to know what's new in the Abaqus 2020 release, please go to our other blog topic. Abaqus 2020: What's new.

Join our online webinar: Meshing native geometry in Abaqus/CAE

Posted by Dolf Broekaart on Nov 27, 2019 9:02:08 AM

This month’s webinar will cover meshing of native geometry in Abaqus. A short section on processing geometry to improve mesh quality will be followed by a discussion of the various meshing techniques available to the user. The webinar will conclude with a brief introduction to the tools available for working with non-native meshes in Abaqus.
