CFD Solver Benchmark and Comparison - OpenFOAM, FEniCS and FEATool

CFD Solver Benchmark and Comparison - OpenFOAM, FEniCS and FEATool

Multi-Simulation and External Solvers in FEATool With the external solver and multi-simulation interfaces, FEATool Multiphysics makes it easy to use multiple solvers which can be suitable for different classes of problems. Using more than one solver can also be very helpful in validating physics models and simulations, …

Modeling and Simulation of Axisymmetric Swirling Flows

Modeling and Simulation of Axisymmetric Swirling Flows

Fluid Flow Simulations with Swirl Effects Fluid flows with swirl effects can occur in rotationally symmetric geometries where the azimuthal or angular velocity component is non-zero. In this case one must solve the fully three-dimensional Navier-Stokes equations. However, due to the assumption that azimuthal variations …

Accurate Computational Fluid Dynamics CFD Simulations

Accurate Computational Fluid Dynamics CFD Simulations

In computational fluid dynamics (CFD) simulations accuracy is often very important, especially for drag and lift values. References [2-3] describe a CFD benchmark problem for time-dependent flow around a cylinder where the Reynolds number varies between 0<=Re<=100. The references contain very accurate reference …
