Software
ANSYS/CFX
The CFD-Lab has many years of experience using CFX to simulate different types of flows in a variety of applications. With a very large set of physical models, CFX has been the first to adopt several advanced models, such as the turbulence models of Shear Stress Transport, Discrete Eddy Simulation and Scale Adaptive Simulation. CFX also shows very high parallel efficiency under Linux and exceptional convergence performance, thanks to its Multigrid Acceleration.
Examples of applications simulated with CFX include:
- Trajectory and deposition of pharmaceutical aerosols in the mouth and throat.
- Trajectory of cough-emitted aerosol particles inside an emergency shelter.
- Multiphase simulation of cough-generated waves in the Airway Surface Liquid.
- Characterization of meteorological instruments under Mars winds for the Phoenix Mission.
- Development and characterization of the Telltale Wind Sensor for the Phoenix Mars Mission.
- Simulation of Mars winds around the Phoenix Mars Lander.
OpenFOAM
Linux in the CFD-Lab
The CFD-Lab adopted Linux as the operating system of choice, because of the rich programming resources offered as part of most Linux distributions and because of the optimal use of CPU performance and memory offered by the OS. For example, CFX has been running in 64bit Opteron processors and in parallel since 2001 under Linux, many years before ANSYS offered similar capabilities for CFX under the Windows OS.
Nowadays Linux offers arguably the most advanced, attractive and user-friendly desktop environments, with plenty of personalization adjustments and many features that improve productivity.
OpenSUSE Installation Instructions
The OpenSUSE Linux distribution is the one preferred at the CFD-Lab. Over the years, this distribution has shown the best compromise between the offer of advanced features, support for new hardware, and convenient, yet powerful system administration tools.
The experience accumulated over the years in the installation and setup of new machines and desktop environments for new users, is summarized in a series of instructions and convenient scripts offered in the links below:
