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 […]

What is a Modal Analysis? What answers do we get out of it? How is it useful? What does it not tell us? In this article, we’ll discuss where a modal analysis comes from, what it is and to some extent what it is not. We’ll also discuss why we do it, what we get […]

More precisely: “How accurately can an FEA (Finite Element Analysis) predict the real response of a structure?” Let’s start by introducing the typical process (chain) of getting from a real structure to an FEA model with results: Set up 3D CAD (Computer Aided Design) geometry of the real structure Simplify the CAD by removing unnecessary […]
