The aim of this study is to explain high-quality time step control i.e. Advanced Mass Scaling (AMS), through an example in Altair Radioss solver. Small element sizes normally lead to small time step in explicit solver and tend to be computationally expensive.

Bolt tightening sequence plays a very important role in proper assembly of parts, as it directly affects the performance of the system. One of the challenges observed in the industry is upon tightening the consecutive bolts, the previous bolts seem to loosen up and also the stresses increase, so it important to follow the right bolt tightening sequence. We are showcasing this by performing bolt pre-tension finite element analysis on two plates bolted at four locations, we are studying the bolt tightening for two sets of sequences, by understanding the bolt forces, stresses, and displacements.
Altair Inspire Cast features many component types that you can include in your casting simulation. One component that can be used to control the solidification of your model is the chiller.
Altair Inspire Cast is a fast, easy, accurate, and affordable simulator for early casting feasibility and process development; it’s a tool that allows you to create a metal casting such as aluminum and steel and incorporate an assortment of different components to run trial and error tests.
When running a metal casting simulation using Altair Inspire Cast, the model needs to be broken up into simple pieces that make up a mesh. In the background, Altair SimLab creates this mesh and delivers it to Inspire Cast for you automatically. For most cases, this process works seamlessly. In this article, we will look at one of the few cases where we bump into a problem caused by some modeling practices that are not well-suited for simulation, and how easy it is to use SimLab to help track down the problem.
Altair SimSolid is a structural simulation that runs its calculation based on original CAD geometry. The geometry does not need simplification like with traditional structural analysis packages because SimSolid does not use a mesh to run its calculations.
Altair EDEM (DEM - Discrete Element Method) is a leading Simulation program used to accurately model the bulk behavior of granular materials as well as how material loading will affect heavy equipment.
