The “Introduction to Optimization for Abaqus Workshop” is a free event for anyone who has some experience with Abaqus and would like to explore the possibilities of optimization. Both non-parametric topology optimization using Tosca and parametric optimization using Isight are discussed, focusing on the optimization of problems using the finite element code Abaqus.

In this post, we will be highlighting the installation and use of the CAD associative interface for interconnecting Solidworks with Abaqus. By using the CAD interface, geometry modifications performed with Solidworks can be transfered in the Abaqus CAE with a push of a button without the need for manually updating previously assigned boundary conditions or interactions.

This months webinar will look at the capabilities of connector elements within Abaqus and how they can be used to simulate mechanisms with complex mechanical behaviours.

On the 5th of July 2018, Simuleon will organise their “Benelux SIMULIA Customer Day”.

During this day, Simuleon’s customers, Dassault Systemes Customers, and other users of the SIMULIA software in Belgium, Netherlands and Luxembourg, are invited to joint us for the latest technological updates and developments withing the SIMULIA Portfolio.

The “Introduction to Non-Linear Analysis Workshop” on the 25th of May 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.

In this post, we will be demonstrating the setup of an earthquake analysis. The structure to be investigated will be a concrete frame. The earthquake input signal will have the form of an acceleration time history (lateral accelerations vs time) with a signal frequency of 100 Hz.

In a previous blog, I have shown how to model welding for a simple case with Abaqus. Here sequential thermal-structural analysis is used to apply temperatures calculated in a thermal analysis in a subsequent structural analysis. Also, the model change option is used to remove and reactivate bead material, simulating its deposit.

A similar approach can be used for more complex cases. However, defining such a model can be very time consuming because many steps with different model changes, film conditions etc. need to be defined.

To simplify the process of setting up such a model, the Abaqus Welding Interface (AWI) has been developed.

In April's upcoming webinar, we will look at the topics related to analysing and assessing Bolted Joints using Abaqus FEA.

Assessments of bolted joints can be performed for a number of reasons. Before starting any FE modelling of bolted joints it is important that the analyst considers the purpose of the analysis and plans it. A summary of typical aspects which should be considered during the planning will be covered.

Part 1: Manual weld definition

Welding is a process that joins materials by causing fusion: the base metal is melted and typically a filler material is added to form a pool of molten material. When simulating the welding process in order to assess the structural behavior of a welded joint, there are two main challenges when setting up the model:

• Thermal and structural behavior needs to be coupled to each other
• Material needs to be added during the welding process. This also changes the boundaries and thus the location of the boundary conditions.

Simuleon has developed a brand new and free half-day workshop, called "Introduction to XFlow CFD".

Our classroom style workshop will be held in English language at our new office location in Zaltbommel, the Netherlands. This is the ideal way to understand and try-out, what advanced CFD simulation, with SIMULIA XFlow CFD can offer.
