The power and cost saving aspect of using Computational Parts can be seen in this quick test. In a quick comparison, a second assembly analysis of 8 parts took only 63% of the time compared to the initial analysis. This was made possible by the computational parts that MSC Apex creates automatically when solving assemblies. […]
The steps below show an overview on how to use Topology Optimization (Design by Mass and Volume) correctly (read Doing Topology Optimization right for more background on this subject). This procedure can be used very successfully to create economically designed parts from scratch with minimum effort. The most important aspect of this process is that […]
See Doing Topology Optimization right for the introduction into this section. In preparation for topology optimization, using load cases exported from Adams or Vi-Rail (see Extracting loads for FEA from Multi Body Dynamics (MBD) Software), the model should have no constraints defined.For this reason, an “Inertia relief” setting is added to enable a static analysis on the […]
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 […]
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 […]
