Topology Optimization of an Abaqus model in Tosca

Posted by Dolf Broekaart on Feb 21, 2017 9:45:00 AM

In the current blog we will show some capabilities of one of Simulia’s extended products, Tosca. As a quick recap, based on your license you can use your tokens to run Simulia Abaqus or you can also use your licenses to run products of the extended portfolio:

  • Abaqus (Finite Element Analysis)
  • Fe-Safe (Fatigue Analysis)
  • ISight (Parametric Optimization)
  • Tosca (Non Parametric Optimization)

How to use Abaqus CEL to model air pressure?

Posted by Christine Obbink-Huizer on Jan 10, 2017 9:32:10 AM
In most simulations, air and the pressure it exerts is not taken into account. There are situations thinkable, however, in which air plays an important mechanical role. An air gun is an example of this: compressed air exerts a force on a projectile, causing it to be propelled. In this blog, I will show how to model air using CEL, using a chamber in which air is compressed with a plug resting on it as an example.

5 Tips for buying FEA Software

Posted by Dolf Broekaart on Jan 3, 2017 9:41:52 AM

This blog focusses on the things that could be useful when considering using, buying or leasing Finite Element Analysis Software. These tips can be used for both future FEA users as well as managers and decision makers who are thinking about starting to use FEA Software, or think about upgrade and expand their existing FEA Software.

For this blog, the following example is used.

Merry Christmas and a great 2017!

Posted by Dolf Broekaart on Dec 19, 2016 5:44:24 PM

This simulation is performed with SIMULIA Abaqus using the CEL - Coupled Eularian Lagrangian technique. Internal pressure is applied to the CEL domain and comes to a burst.

Material calibration using Abaqus (and Isight)

Posted by Christine Obbink-Huizer on Nov 22, 2016 12:37:18 PM

When performing a finite element analysis many modelling choices must be made. One of them is the choice of material properties. This can have a big influence on the outcome of the simulation. In many cases some material properties are known, for example in a data sheet. These normally do not directly correlate to the parameters required by Abaqus. When not all the required material properties are known, experimental data must be obtained. Based on this data, a material model and material parameters must be defined.

Post-processing - Part 2 in Abaqus - Join our Webinar

Posted by Dolf Broekaart on Nov 15, 2016 4:39:49 PM

On the 25th of November at 11.30 a.m. we will host our Post-processing – Part 2 in Abaqus Webinar. In this webinar, we will continue to look at advanced techniques available in Abaqus/Viewer such as animations, results computations and user-defined field outputs. We will also look at other ways of post-processing the analysis results such as using the .dat file. Finally, we will present the new features that will be available in Abaqus/Viewer 2017.

Abaqus FSI Drop Test - 100 liter HDPE Fuel tank

Posted by Dolf Broekaart on Oct 21, 2016 4:28:23 PM

This blog shows how we performed a drop test for a Polyethylene 100 liter Fueltank containing fluid with SIMULIA Abaqus FEA Software. The goal of this analysis is to predict the possible material behaviour and failure that will lead to leakage.

This example involves a fluid-filled plastic tank falling from a height of roughly 15 meters onto a flat, rigid floor. The tank as shown in the pictures below is made of high-density polyethylene with a wall thickness of 5 mm everywhere. The tank is filled almost completely (about 90%) with water. A realistic simulation for the tank must account for both the exterior forces on the tank from the floor impact, as well as the interior forces of the water pushing against the walls of the tank. Resulting stresses and strains in the tank will be used to determine its structural feasibility.
