Automate boring postprocessing in Abaqus using python scripting

Posted by Christine Obbink-Huizer on Oct 5, 2018 1:58:40 PM

One of the benefits of doing simulations, is that it is easy to change various parameters to assess their influence on results. When doing this, often the same post-processing is needed for more than one analysis. Of course you can manually open each .odb, create the right images and save them, but this can be quite a lot of (boring!) work and the chance of making a mistake is definitely there. Therefore, it is often beneficial (and more fun) to create a script to do this automatically. In this blog, I will show how you can create a script to automate the creation of images using Abaqus.

Modeling Bolted Connections with Abaqus FEA

Posted by Nikolaos Mavrodontis on Sep 18, 2018 9:15:15 AM

In this blog post, we will be discussing about the different methods in modeling bolted connections with Abaqus FEA. At the last section of the post,we will be showcasing a bolted connection, incorporating a pretensioned bolt. Flanged connections are used extensively in most engineering disciplines. They provide a way of interconnecting  various (metallic, plastic etc.) components and their design is often critical for the strength of various components (e.g. bolt strength) and sealing of the assembly.

Join our hands-on workshop: From Testing to Finite Element Analysis for Rubbers with Abaqus

Posted by Dolf Broekaart on Sep 13, 2018 12:46:28 PM

 

On Friday the 26th or October, Simuleon and Elastomer Research Testing (ERT) are hosting the free hands-on workshop ‘From testing to Finite Element Analysis for Rubbers with Abaqus ’. In this unique co-hosted event Simuleon will present their solutions based on the SIMULIA portfolio and ERT will present their Rubber testing capabilities to gain material specifications for usage with SIMULIA Abaqus FEA.

Starting with a lecture session covering the essential concepts of advanced simulation for Rubbers, the course also gives the attendees the opportunity with our hands-on workshop, to model advanced phenomena such as non-linear elastic behaviour & material calibration, in-compressibility, element selection, shrink-fit & pressure penetration and other highly complex events with SIMULIA Abaqus.

4 Questions to ask when doing finite element analysis (or problem solving in general)

Posted by Christine Obbink-Huizer on Aug 29, 2018 5:15:03 PM

Let’s start with a problem:

“A ladder hangs over the side of a ship anchored in port. The bottom rung of the ladder touches the water. The ladder is 30 cm wide and 270 cm long. The rungs are 1 cm thick and the distance between them is 34 cm. If the tide is rising at a rate of 15cm per hour, how long will it be before the water reaches the top rung?”

Introduction to Non-Linear Analysis - Join our Abaqus Workshop - 31 Aug 2018

Posted by Dolf Broekaart on Aug 20, 2018 9:20:58 AM

The “Introduction to Non-Linear Analysis Workshop” on the 31st of Aug is a free event 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.

Symmetric model generation with Abaqus

Posted by Nikolaos Mavrodontis on Aug 6, 2018 5:04:11 PM

In this blog post we will be discussing about the symmetric model generation feature that is incorporated in Abaqus. This feature is targeted towards reducing the solution time needed for an analysis. We will first present the supported features and limitations, followed by an exemplary analysis of a flanged connection wherein this feature can be used.

Join our "Abaqus Buckling, Postbuckling and Collapse Analysis" Classroom Training - 16 & 17 August

Posted by Dolf Broekaart on Jul 30, 2018 4:22:11 PM

At the 16th & 17th of August 2018, Simuleon will hold a 2-day classroom training at our location in Bruchem, The Netherlands. The training is called "Abaqus Buckling, Postbuckling & Collapse Analysis Training".

Buckling and postbuckling behavior is critical to the success of certain designs. For example, crash worthiness of an automobile requires that particular vehicle components collapse in ways that maximize energy absorption. On the other hand, successful designs of imperfection-sensitive, thin-walled shell structures, ranging from beverage containers to large pressure vessels, must prevent unintentional buckling.

Join our online webinar: Civil Engineering with Abaqus FEA - Part 2

Posted by Dolf Broekaart on Jul 23, 2018 1:37:26 PM

In the previous webinar on civil engineering and Abaqus, we covered the basic topics in modelling buildings and infrastructures. First we introduced the principal material models used in this field, with a focus on the Concrete Damaged Plasticity model. Structural elements – in particular beam and shell elements – have been described in detail, presenting several special applications and the construction of the model of a steel framed building. Also, a detailed description of different techniques used to model reinforced-concrete were described. 


In this second part of the webinar we will focus on some specific applications. Common techniques to model pre and post tensioned tendons will be presented. Examples include a prestressed RC beam, a post-tensioned concrete slab and a post-tensioned reinforced concrete nuclear containment vessel.

7 tips to help Abaqus run faster

Posted by Christine Obbink-Huizer on Jun 29, 2018 4:06:20 PM

Maybe you recognize this: you set up your model, start running the job, open the monitor window and ... it stays empty, longer than you would like. The simulation is taking longer than you hoped or expected and you wonder: "how can I do this faster (without significantly reducing the accuracy of the results)?" In this blog I'll discuss some ideas and experience we've had related to simulation speed.
