By Daniel Kowollik, Lead Engineer, Blade, Bewind, and Fabio Pavia, Senior Product Manager, Ansys Wind energy is one of the world’s most promising sources of renewable energy. Interest in this emission-free natural resource has grown even more as concerns over air quality and climate change continue to rise globally. As Read more…
Aneurysm Clipping Clipping is a tried-and-true method of treating an aneurysm, a bulge in a weak area of an artery. Artery walls are under constant pressure from the high-pressure blood flow inside them. The constant pressure can cause a weak area of the wall to balloon out, forming an aneurysm. Read more…
“By simulating the flow of blood through the different designs in Fluent and visualizing the outcomes in CFX, the researchers at The Kidney Project could measure blood flow velocity precisely, identify areas where clots were likely to form and understand why those spots created opportunities for clotting and then incorporate Read more…
ANSYS ADVANTAGE MAGAZINE By Ansys Advantage Staff Each year, thousands of people die as a result of aortic aneurysms — balloon-like bulges caused by weaknesses in the aortas, the large artery that sends blood from the heart through the vascular system. If an aneurysm remains undetected, the aorta can eventually tear Read more…
Endovascular Coiling Endovascular coiling is a procedure performed to block blood flow into an aneurysm (a weakened area in the wall of an artery). Endovascular coiling is a more recent treatment for brain aneurysms; it has been used in patients since 1991. Endovascular coiling is a minimally invasive technique, which Read more…
Reynolds-averaged Navier–Stokes (RANS) equations Turbulence modeling is one of the main sources of uncertainty in CFD simulations of technical flows. This is not surprising, as turbulence is the most complex phenomenon in classical physics. Turbulent flows pose a multi-scale problem, where the dimension of the technical device is often of Read more…
Description of geometric indices Parent vessel geometric characterization Given the 3D surface model, vessel centerlines are computed for all the available segments and are available for download on the website. Only the tract hosting the aneurysm is used for the geometric characterization. The segment under investigation is extracted from the Read more…
What is a cerebral aneurysm? A cerebral aneurysm is a bulge in a weak area of the wall of a brain artery. It puffs out like a small balloon and fills with blood. It is also called an intracranial aneurysm or brain aneurysm. This bulge makes the artery more likely Read more…
Mesh Generation Mesh or grid is defined as a discrete cell or elements into which the domain/ model is divided. All the flow variables & any other variables are solved at centres of these discrete cells. This entire process of breaking up a physical domain into smaller sub-domains (elements/ cells) Read more…
What is Cavitation? Cavitation happens when vapor bubbles form in a liquid because flow dynamics cause the local static pressure to drop below the vapor pressure. Without accurate prediction of cavitation, users cannot effectively optimize designs and set operating parameters and limits, potentially exposing their products to unexpected vibration and Read more…
