🔻OpenFOAM® MinGW cross-compilation

Installing the cross-compiled OpenFOAM package is the easiest method to obtain the latest OpenFOAM version on Microsoft Windows systems, requiring no virtualization of any kind.

Applications are directly executable and accessible from a Windows terminal (cmd) or, preferably, via the MSYS2 terminal (part of the OpenFOAM installation) which offers the power of Linux command line tools.

To post-process simulation results users are advised to install the Windows version of ParaView. Similarly, other graphical tools such as Gnuplot should be installed separately.

SIGGRAPH (Special Interest Group on Computer GRAPHics and Interactive Techniques) is an annual conference on computer graphics (CG) organized by the ACM SIGGRAPH, starting in 1974. The main conference is held in North America; SIGGRAPH Asia, a second yearly conference, has been held since 2008 in countries throughout Asia.

Getting wet can be a problem for many animals. A wet insect could quickly become too heavy to fly, and a wet bird can struggle to stay warm. But these animals have a secret weapon: tiny, multi-scale roughness on their wings, scales, and feathers that helps them shed water. Watch the latest FYFD video to learn how!

A Dockerfile that adds swak4Foam and PyFoam to regular OpenFOAM images:

Adds swak4Foam and PyFoam to Standard OpenFOAM docker containers. Maintained by the creator of those two packages.

The sources for these docker containers are on Bitbucket and the containers are on Docker Hub

Currently, the latest supported version is OpenFOAM v1912+ and OpenFOAM 7.0

This visualization, from a collaboration between #NASA and #Boeing about airframe noise prediction, shows the simulated air flow field around the nose landing gear of a Boeing 777, representing the complex unsteady flow generated by the gear components. The visualization is q-criterion colored by speed, from slower green to faster red air velocities. A strong vortex appears coming off the edge of the landing gear doors. Simulations run on NASA supercomputers at Ames allow researchers to better understand the changes in flow behavior that contribute to airframe noise.
