The development of microfluidic devices for the life sciences industry has a promising future. The industry has seen an increase in R&D spending for novel concepts, which are on the rise.This online event will show why numerical simulations have become critical for pinpointing key requirements for successful implementation through both prototyping and optimization. From developing medical test strips, analyzing implanted sensors and drug delivery, developing lab-on-a-chip models, to prototyping new concepts or designing PCR bioreactors, presenters will show how advanced simulation can...
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...

. In many applications there is a need to simulate transient flows around bodies over a longer period. While the flow usually takes place in a large domain, engineers are usually interested only in the solution in the immediate vicinity of the body. It is therefore very important to be able to reduce the size of the computational domain and thus reduce the computing effort while not compromising the accuracy and reliability of the solution. This paper describes one approach which can be applied, among others, to flows around floating or flying bodies. The idea is to force the solution of the...
CFD Simulation for Flow Assurance & Subsea Engineering
Reliable subsea system and pipeline design and effective flow assurance strategies are integral to successful deepwater oil and gas exploration and production. Remote environments and extreme operating conditions combined with high pressure, high temperature (HPHT) wells often present significant engineering challenges. Today’s lower oil prices, putting pressure on R&D budgets, are pushing companies to reduce product and solution development costs, without compromising quality or safety. Leading engineering companies address these challenges through the use of engineering simulation...
