🔻 Notable changes to OpenFOAM-dev

🖊 Packaged OpenFOAM-dev and v6 for Ubuntu 18.04/18.10, with ParaView 5.6.0, including Mesa with LLVM/Gallium acceleration for systems without a (supported) graphics card; installable on Windows 10, with Docker images for other Linux and MacOS [ more... ]

🖊 In the mesh utilities, rationalised the field handling code and added a -noFields option [ commit 66c26a ]

🖊 Added sources to k and omega equations in the kOmega model to make it easier to derive models from it [ commit f5d684 ]

🖊 For multiphase reacting flows, added heat transfer model with a constant Nusselt number, with VTT Finland [ commit 0dfde5 ]

🖊 Rationalised code for sampledSurface, to maintain visualisaition post-processing functionality [ commit 8baec3 ]

🖊 Improved the setup of tutorials with reactions [ commit 14aad1 ]

🖊 Mesh motion can include multiple motion solvers, e.g. solid body rotation and deformation with prescribed boundary motion [ commit faf6e2 ]

🖊 Improved the numerics, chemistry and general configuration of the reverseBurner tutorial, which includes conjugate heat transfer and combustion [ commit a08502 ]

🖊 Added Qdot function object to write out heat release rate field due to combustion [ commit dc25f1 ]

🖊 Improved the population balance phase change drift model in multiphase flow, with VTTFinland [ commit 5e2f17 ]

🖊 Improved stability of interfacial heat transfer in multiphase flow, particularly for cases with high mass transfer rate, with VTT Finland [ commit 7e799e ]

🖊 Generalised a reusable timeVaryingMappedFvPatchField boundary condition for mapping data at a set of supplied points in space and time onto a patch [ commit 8b4f86 ]

🔻Superfluidity is the characteristic property of a fluid with zero viscosity which therefore flows without loss of kinetic energy.

🔻When stirred, a superfluid forms cellular vortices that continue to rotate indefinitely

🔻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!
