We must often strike the right balance between the computational time and accuracy of our simulation. Simplification/removal of unimportant CAD features, locally refined mesh, and usage of equivalent elements are some proven methodologies to reduce the calculation time. If the … Read More
According to Wikipedia, “Multiphysics is a computational discipline which treats simulations that involve multiple physical models or multiple simultaneous physical phenomena. For example, combining chemical kinetics and fluid mechanics or combining finite elements with molecular dynamics. Multiphysics typically involves solving coupled systems of partial differential equations.” What does this imply for … Read More
Standard FEA methods simulate bolt geometry and bolt physics in a very simplistic way. The bolt is usually replaced by either a rod or beam element which is in turn connected at its ends to other parts via many other … Read More
As CAE engineers, we are proud of how we manage to tame the laws of nature in our models, but let’s face it – not everyone shares our passion for complex meshed models in sixty-four colors, cluttered with multi-point constraint … Read More

There has long been a debate in engineering, whether incremental improvement or new design is better for approaching a project. The incremental approach is often less expensive, less risky, and faster, which are all attributes valued by business. On the … Read More
This article was first published on Desktop Engineering. Simulation-driven design — the philosophy of using simulation tools upfront in the design process to find the ideal design solution fast — is something we talk a lot about at Altair. It’s something the … Read More
