Orthotropic Heat Conduction
Orthotropic Heat Conduction
This is an example of modeling anisotropic heat conduction in an orthotropic material where a heated solid bar suddenly is cooled by submerging it in a cool fluid. The material features different thermal conductivities in the x and y-directions which is accounted for by modifying the diffusion term in the heat transfer …
Turbulent Channel Flow
Turbulent Channel Flow
Simulation of stationary and incompressible turbulent flow between two parallel flat plates at Reynolds number 42800. A fully developed turbulent velocity profile is formed at the outflow boundary which can be compared to experimental results (Laufer, J. 1950). This example uses both the built-in algebraic mixing …
Simulation of Heating to Promote Drug Mixing in the Eye
Simulation of Heating to Promote Drug Mixing in the Eye
The leading cause of central vision loss in the developed world is from age-related macular degeneration (AMD). Although certain types of AMD can generally be managed with injections of anti-VEGF agents, the treatment is sometimes ineffective. The linked study examines how this type of treatment potentially can be …
Fluid-Structure Interaction - Elastic Beam
Fluid-Structure Interaction - Elastic Beam
Fluid-structure interaction benchmark problem for stationary, laminar, and incompressible flow around a cylinder with an attached elastic beam. Although it is not possible to derive an analytical solution to these test cases, numerical solutions to benchmark reference quantities have been established for the beam …
Thermo-Mechanical Bending of a Beam
Thermo-Mechanical Bending of a Beam
Coupled thermo-mechanical multiphysics simulation of bending of a cantilever beam. The left side of the beam is fixed to a solid wall while the top side is subjected to an elevated external temperature through natural convection. The lower and left side are continuously held at the initial zero temperature. A …
Multiple Scale Modeling for Predictive Material Deformation Analysis
Multiple Scale Modeling for Predictive Material Deformation Analysis
A multi-scale modeling and simulation study using FEATool Multiphysics to investigate stretching and deformation of a ligament under uniaxial tension is presented in the following. The study demonstrates how the FEATool simulation software can be used by students and non-experts to perform simulations and quickly get …
Turbulent Flow Over a Backwards Facing Step (OpenFOAM)
Turbulent Flow Over a Backwards Facing Step (OpenFOAM)
Flow over backwards facing steps are classic computational fluid dynamics test problems, and are often used for validation of simulation codes. This test problem consists of studying how the flow field reacts to a sudden expansion in a channel. The expansion will cause a break in the flow and a recirculation or …
