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 […]

More and more problems need to be solved by using advanced non-linear simulation tools like Marc from MSC Software. Marc has powerful auto-remeshing capabilities to ensure the integrity of the finite element formulations regardless of the amount of deformation that occurs due to large strain and deformations. Add thermal aspects or fracture mechanics, electromagnetics or […]
