Local surface remeshing allows for remeshing only selected areas when changing mesh parameters or performing design changes, reducing surface mesh generation time up to an order of magnitude and a key enabler of efficient design space exploration.
Good (and bad) Vibrations: Designing for Flow Induced Vibration with Simulation
Flow Induced Vibration (FIV) is a design concern for piping networks, such as jumpers and manifolds. When the piping is deployed subsea, obtaining an accurate understanding of FIV is imperative, since failure and subsequent remediation is costly at best, and likely infeasible. Simple methods, such as the Energy Institute (EI) guidelines, are used to assess the likelihood of FIV. However, these are highly conservative, potentially leading to unnecessary additional costs. In recent years CFD tools have been used to predict the multiphase flow in the pipelines, forcing on the pipe, and the...

The What, Why and How of Simulating Joule Heating
Any device that uses electrical power experiences energy loss to heat. A primary physical phenomena causing this is known as Joule (or ohmic or resistive) heating, and it can be either advantageous or detrimental for a given system. Some applications - such as fuses, floor heaters, heat lamps, and window defrosters - rely on Joule heating for their operation. In other applications - including bus bars and high-power printed circuit boards - Joule heating is an inevitable side effect that must be predicted and managed if the product is to perform reliably. This webcast explores the physical...
Cylindrical DEM Particles in an Auger
Cylindrical DEM Particles in an Auger
Until the release of STAR-CCM+ v11.02, composite particles were needed when modelling anything cylindrical and, to get a realistic representation, this required a large number of spheres.With the introduction of cylindrical particles in v11.02, users will experience increased accuracy and reduced computational time, a rare win-win situation in simulation.
A Better Understanding of Particulate Flows and Fluid Flows
Coupling Computational Fluid Dynamics (CFD) with Discrete Element Modeling (DEM) is a powerful combination to investigate the effects of particulate flows and fluid flows. This webcast highlights how these technologies have been applied to shorten product process development cycles and reduce energy requirements. Presenters demonstrate using a Rotary Kiln within the context of the DEM-CFD model. They will explore how optimizing these existing processes results in the efficient design of new products. For large-scale chemical products, it can also mean less waste, as well as a reduction in the...
With STAR-CCM+ v11.02, you can now combine two or more materials when simulating extrusions, enabling the analysis of more complex products targeted to very specific applications. For example, multi-luminal medical tubing has very narrow tolerances and needs to meet the highest quality standards. Consequently, it’s critical to understand how design changes to the die profile or variations in feedstock properties can impact end product quality.
GET FIRED UP! Combustion Simulation in the Process Industry
Increasing energy efficiency, reducing environmental impact, enabling fuel flexibility and improving system reliability are the common design goals of the chemical industries and of combustion systems in process (glass, steel, cement, metallurgy, petroleum refining, industrial gases).* Computational Fluid Dynamics (CFD) and reaction kinetic simulations of combustion processes offers a methodical approach in designing such systems by lowering the cost of iterating between trials and prototypes. Furthermore, recent advances in CAD maneuverability and optimization algorithms have further...
