When, a few weeks ago, I was asked to present at a joint marketing event with CD Adapco in Aberdeen, a subject wasn’t too hard to choose. How things are changing in the analysis of valves and the world of ASME seemed like an obvious thing to talk about.

February’s webinar will be held on February 27th at 10:30 and will be entitled: “Advanced contact webinar: main convergence issues”.
Contact is the most common source of nonlinearities and one of the major concerns for any finite element analyst. Sudden contact changes lead to abrupt increases or reduction of the stiffness matrix of the system resulting in convergence issues, especially if an implicit solver is used. Moreover, correctly handling complex contact conditions may extremely reduce the computational costs of a finite element analysis.
In this webinar, we will have a look at the main convergence issues related to contact modelling such as initial rigid body motions, dynamic instabilities and overclosures due to inadequate geometries. For each topic, the main modelling strategies available in Abaqus will be presented. Example cases and demonstration of use will be provided throughout the webina.

I remember how business was back in 2009.  Global recession was biting and affecting everyone.  It seemed that everyone had stopped buying new cars, and that most people had chosen to avoid flying, where possible, so both the auto and aero markets were in disarray.

At SSA we want to work together to develop your understanding and knowledge by introducing you to the Simulation portfolio within Dassault Systèmes SIMULIA to show you solutions to complex analysis problems.

This is covered by the Dassault Systèmes SIMULIA brand with, Abaqus, Isight, Tosca and fe-safe covering Non Linear, automation, optimisation, fatique and multiphysics.
