New FEA Material Models | SimScale Platform Update 04/2015

BlogAbout SimScaleNew FEA Material Models | SimScale Platform Update 04/2015

The SimScale team is constantly working on enhancing the simulation capabilities of the SimScale simulation platform to meet our user requirements and make the simulation more simple, efficient, and affordable. We really value your feedback. Therefore, we are excited to highlight a few additional features and resources from the latest SimScale platform update, that you have been asking for.

New FEA Material Models

Pressure vessel simulation - SimScale Platform Update 04/2015 — New FEA Material
Material creep plays a role in the long-term behavior of pressure vessels

The tendency of specific materials to progressively deform over time under constant load is called creep. Creep material models have been added to the solid mechanics analysis types on SimScale. These FEA material models allow engineers to simulate this phenomenon and therefore assess the long-term behavior of structures under constant loads.

LES Turbulent Flow Simulation

The first large eddy simulation (LES) capabilities have now been made available for the simulation turbulent flows. The Smagorinsky and Spalart-Allmaras models are the first ones, but more are about to follow. Where the RANS (Reynolds-averaged Navier-Stokes) approach does model all scales of a turbulent flow, LES resolves some of the larger scales, allowing higher-fidelity simulations. However, this also results in longer computing times.

New Pricing Plans Available

To provide more flexibility to the SimScale users, we have recently launched new pricing plans. The annual computing quota was the one requested the most-frequently requested feature, so you asked and we delivered. The new plans allow for a more efficient use of the available computing quota. You can see all the details on the plan page or reach out to the SimScale sales team.

More Validation Projects

To ensure accurate results, the SimScale platform is constantly validated with numerous projects. Week by week, our engineers are adding more of them to increase the validation coverage. Lately, many of the projects have been made publicly available. This allows any SimScale user to import the projects he or she is interested in and to repeat the setup. The images below show the Ahmed body, which is an aerodynamics validation scenario for external vehicle flow. The image in the middle shows the compressible flow through a Laval nozzle. The image on the right shows the Couette flow setup, which is a case used to validate rotating flow simulation capabilities.
