Computational fluid dynamics modeling is based on the principles of fluid mechanics. It utilizes numerical methods and algorithms to solve problems that involve fluid flows. CFD models attempt to simulate the interaction of liquids and gases where the boundary conditions define the surfaces.
Aneurysm Coiling Treatment We are pleased to inform you that our article “Influence of the coiling porosity on the risk reduction of the cerebral aneurysm rupture: computational study” has been published in Nature Scientific Reports and is available online.The open-access paper has just been published today and you can read 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…
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…
UDF A user-defined function, or UDF, is a C or C++ function that can be dynamically loaded with the ANSYS Fluent solver to enhance its standard features. For example, you can use a UDF to: Customize boundary conditions, material property definitions, surface and volume reaction rates, source terms in ANSYS 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…
3D Blood Flow Simulation Bio-medical researchers have been relying on computational fluid dynamics to model and understand the physical mechanisms behind the formation and progression of hemodynamic disorders. Wall shear stress (WSS) exerted on the walls of the blood vessel due to the flow of blood is one of the Read more…
Pressure The pressure could be measured by different devices such as barometer, piezometer and Pitot tube. A barometer is a scientific instrument that is used to measure air pressure (atmospheric pressure) in a certain environment. Pressure tendency can forecast short term changes in the weather. The atmospheric pressure (ambient pressure) causes the fluid Read more…
