One warm July morning buddy of mine and I decided that we needed to hit the lakes and go catch "the big one". We headed out just as dawn broke so we can find that big old bass that I knew was hidden somewhere in our favorite spot. Once we got the boat in the water it is about a 15 minute ride across the lake over to the spot where our fish was bound to be. So a cup of coffee in hand we sped off across the lake, during that time one’s mind always tends to wander and apparently mine wanders back to meshing. Looking across the still lake nothing much is going on but behind the boat is a whole different story; the propeller is stirring up quite a bit of turbulence and the hull is producing a massive wake, this is where the action is. So I ask to myself, what kind of tools would our users need in order to build meshes automatically in order to capture this type of phenomena? A tool that would allow efficient meshes and could give accurate answers with a minimal cells count. STAR-CCM+ v10.02 meshing operation allows users to refine wake zones in both the polyhedral and the trim meshers as well as give wake a draft angle so that the refinement zone expands as it moves away from the model.
In v10.02, we have a new feature, adjoint error estimation, which leverages the power of adjoint to highlight discretization errors in your mesh that may be due to inappropriately sized and distributed cells. These discretization errors may, in turn, affect the accuracy of your engineering results.
Better Designs for Flow, Heat and Combustion in Coal-fired Power Plants
Various processes in the life cycle of coal such as mining, pre-treatment, combustion and flue gas aftertreatment can be simulated with computational fluid dynamics (CFD) to explore and discover better designs, faster. This webcast will focus on specific ways by which CFD simulations can help increase the efficiency, reliability and longevity of coal-fired power plant systems while decreasing emissions. Case studies and application examples pertaining to simulating coal-combustion in burners, including a comparison to experimental results from a well-known International Flame Research...
Realizing the Benefits of Overset Mesh in Aerospace and Defense
Overset Mesh technology (or Chimera Mesh, if you prefer) has been around for decades but has primarily stayed in a small, niche aerodynamics community. Although powerful in their own right, overset mesh tools to date have been purpose-built for specific applications and, let’s face it, a bit tricky to use. A live demonstration shows the entire Overset Mesh CFD analysis process – including geometry preparation, meshing, solving and post-processing. We explore the benefits of Overset Mesh through several application cases, including: Aircraft/spacecraft separation events Aircraft control...
We employed computational fluid dynamics (CFD) and finite element method (FEM) to investigate the hemodynamic effect of two flow-diversion strategies of cerebral aneurysm treatment: overlapping stents and dense compaction of a single stent. Three representative patient-specific aneurysms were used as test cases, and flow diverters were virtually deployed into the models. Aneurysmal hemodynamic modification by flow diverters is strongly correlated with the metal coverage rate across the aneurysm neck, and not uniquely determined by FD deployment strategies. Fusiform aneurysms may be more...
A new realistic finite element method (FEM) based endovascular coil deployment technique was developed to explore the hemodynamic modifications of coiling in addition to flow diverter (FD) treatment. A patient-specific internal carotid artery aneurysm was used as a test case, and a single flow diverter was deployed using a previously developed method , along with several coils using the new method. Results showed fluctuations in hemodynamic parameters at low packing densities (1-3 coils) which are unexpected. At high packing density however (6 coils), results were consistent with expectations...
An aneurysm is a localised dilation of an artery wall that is life threatening when ruptured. Iliac artery aneurysms (IAA) may occur in isolation, but often accompany other large artery aneurysms, such as abdominal aortic aneurysms (AAA). For people over 65 years, the prevalence of AAA is high, at approximately 5–6% for men and 1–2% for women. Of the iliac arteries, aneurysms often occur in the common and internal iliac arteries, but are rarely found in the external iliac arteries. These three arteries are in close proximity to each another, and there is no obvious explanation as to why...
