The Abderdeen group has found that on average, analysts across industries spend up to 80% of their time on CAD clean-up for analysis purposes. MSC Apex Modeller has proven without a doubt that it brings a new way of editing (and creating) geometry which rapidly improves the created meshes and within a much shorter time […]

Nonlinear runs tend to require anything from tens of iterations to thousands of iterations to complete. Reducing the number of iterations to convergence and reducing the time per iteration will speed up a run. In this article we’ll discuss some ways to speed up iterations and leave reducing the time per iteration to a subsequent […]

This article is part of a series on the use of Marc and Mentat. Because Marc can solve such a large set of physics, the number of things that can go wrong is pretty large. In this first article we’ll be looking at convergence problems and how to overcome them. Introduction Getting linear FEA (Finite […]

We have all learnt through our careers with FEA (Finite Element Analysis) that "tria3 elements are bad" and that "quad4 elements should stay square" for better results but how much worse are tria3 elements (and under which circumstances?) and exactly how bad is a deformed quad4 element when it comes to the results we obtain […]

"Topology Optimization" is the formal term for the technology that allows you to say to the computer: "Take this chunk of material, with all these different loads and take all the unnecessary material away". Have you ever wondered how car manufacturers manage, with every new car model, to make the cars lighter and yet stronger? […]
