In engineering consulting, troubleshooting the problems faced by your customer in an efficient, timely manner is the bread and butter of the business. As such, it is highly critical to be equipped with the right tools in addition to having competent engineers tackling the problem. This article showcases one such example where a modern numerical simulation software in the hands of good engineers transforms into an efficient, effective virtual troubleshooting tool. Zeeco Inc. is a provider of combustion and environmental solutions, involved in the engineering design and manufacturing of burners...
For downsized SI-engines at high loads and particularly at low engine speeds, spontaneous auto-ignitions randomly occur before the regular spark timing, leading to severe engine damage. These preignitions are limiting the fuel efficient combustion process and therefore it is crucial that the underlying mechanisms are understood. Dynamics 37 - Read more...
The birth of the Can-Am®Spyder® roadster defined new paradigms. Combining the open-air benefits of a motorcycle with many of the convenient features of a traditional roadster created a totally new product category of on-road power sport vehicles. Dynamics 37 - Read more...
A common difficulty in the simulation of complex fluid flow problems is that not every geometry can be well represented using a single, contiguous grid. This is especially true for the case of relative motion between components. Overset grids can be used to track relative motions with computational efficiency and recent advances in high performance Computational Fluid Dynamics (CFD) software like STAR-CCM+® have enabled the coupled simulation of multiphase fluid flows and rigid body motions using overlapping overset grids. A CFD method was developed and applied for the simulation of oil flow...
Creaform was asked to assist in the design of a cleanroom, by performing a complete 3D reconstruction of the geometry of the room, and using this to carry out detailed CFD simulations. The cleanroom in question is used in the manufacturing of influenza vaccine, and the aim of the study was to design an efficient aerodynamic barrier that would mitigate the risk of contamination. The demonstration was convincing and CFD simulations shed light on phenomena that traditional smoke tests, still used for regulatory compliance of pharmaceutical environments, had never been able to resolve before...
Cements are commonly used in dentistry, but there is very little knowledge of how their flow patterns influence the performance of dental systems. One area in dentistry where shape optimization should be considered is cementing of implant restorations. It has been shown that extrusion of excess cement at the crown-abutment margin during the seating of a cement-retained crown over an implant is a major cause of peri-implant disease . Recent advances in simulation are now enabling an increased level of insight into the details of the cement flow in these complex systems, opening the door for...
Canal de pruebas Virtual: Cómo el CFD puede auxiliar tu proyecto en cumplir con los requisitos del EEDI sin comprometer la velocidad de operación del buque En Enero de 2013, la IMO ( International Maritime Organization ) presentó el concepto del EEDI ( Energy Efficiency Design Index ) como una forma de evaluar la eficiencia energética de los nuevos buques. El objetivo del reglamento EEDI es reducir las emisiones de CO 2 . Esto obligaría a diseñadores e ingenieros reducir el tamaño del motor (consecuentemente las emisiones) o las velocidades de operación de los buques. En este Webinar se...
Canal de Provas Virtual: Como CFD pode auxiliar o seu projeto a atender aos requisitos EEDI sem comprometer a velocidade de operação da embarcação Em janeiro de 2013, a IMO ( International Maritime Organization ) apresentou o conceito do EEDI ( Energy Efficiency Design Index ) como uma forma de avaliar a eficiência energética de novas embarcações. O objetivo da regulamentação do EEDI é reduzir as emissões de CO 2 . Isso muitas vezes leva projetistas e engenheiros a reduzir o tamanho do motor e, consequentemente, as emissões. No entanto, pode também penalizar as velocidades de operação. Este...

In my last blog I spoke about some of the improvements to our design exploration tools. For version 9.06 of STAR-CCM+, we have worked on another facet of design exploration, by improving the usability of our mesh morpher which allows you to more easily perform free-form, non-parametric, deformation of your geometry. At the beginning of the year we released the mesh deformation model which enabled you to change the shape of your geometry using morpher. This is an important capability as you may not always have access to the raw CAD data, or indeed the software required to modify it.
