Structural mechanics FEA simulation for design of Push-Pull robots
This paper explores the design of “concentric push-pull robots” designed to make endoscopic surgery easier, such as biopsies or to removing polyps. In contrast to using colonoscopes which are difficult to maneuver, and may lead to longer procedure times and a higher chance of needing additional more …
Thrombosis risk assesment with FEATool Multiphysics CFD simulation using PIV data
The following research, conducted by Borowski F., Kaule S., and colleagues concerns a type of heart valve that can be inserted without open-heart surgery (transcatheter aortic valve replacement TAVR). The researchers wanted to see if the way the valve is inserted affects how well blood flows through it, specifically …
AI and Deep Learning CFD Model for Flow Prediction
In a series of publications Prof. Thi-Thu-Huong Le, Hoyeun Kang, and colleagues from Pusan National University (PNU) in Korea, have successfully developed a new deep learning (DL) CFD methodology for flow prediction using FEATool Multiphysics with AI and machine learning. Although traditional Computational Fluid …
Supersonic Turbulent Flow Past a Prism
This tutorial example sets up and solves supersonic compressible flow around a triangular prism, with viscous effects and turbulence using the OpenFOAM solver. The inflow is supersonic at 650 m/s causing shock waves to form when the flow field impacts the prism, and also secondary waves following the trailing edges and …
Supersonic Flow Past a Wedge
This verification test case studies steady inviscid compressible flow past a wedge at an incident angle of 15 degrees. As the supersonic flow (Ma = 2.5) hits the wedge a sharp oblique shock wave is formed, resulting in a reduced downstream flow velocity. The simulation uses the inviscid compressible Euler equations to …
Surface Currents in a Circular Wire
Skin effect is a phenomenon where an alternating current tends to flow and distribute itself along the surface layer or outside skin of a conductor. This effect can for example be taken advantage of in power transmission applications by layering inexpensive conductor materials (for example aluminium) with a thin layer …
Multi-body System Simulation for Design of Optical Grating Tiling Devices
A grating tiling device is an optical element which can separate light into different wavelength components. Such devices are for example used in spectroscopy, and in optical laser devices for fusion confinement. Due to the high sensitivity and precision required in these devices, stability with respect to vibrations …
Non-Newtonian Flow in an Extrusion Die
This example models flow of a polymer through an extrusion die with two outlets. This type of flow can for example be found in manufacturing processes of plastic parts. The polymer is assumed to be non-Newtonian, and can be modeled with a shear thinning Bird-Carreau viscosity model. The die is also assumed to be …
Temperature Loading of a Tapered Cylinder
This validation test case models temperature loading of a tapered hollow thick cylinder with a spherical bottom flange section. The solid object is assumed to be clamped vertically, but allowed to expand horizontally due to a linear temperature gradient. The stress in the z-direction at the bottom inner point is …
