OpenFOAM-v2012 released
 

ESI OpenCFD Ltd. is pleased to announce the release of OpenFOAM-v2012.

The version released in December 2020 brings a lot of exciting new functionality and extension to the existing ones. Let us, among others, highlight a few:

In Meshing:

• SnappyHexMesh - New thicknessModel allowing more precise y+ control in the first-cell layer
• SnappyHexMesh - Improved control of gap refinement
• extrudeMesh - New polyLine extrusion model allows to specify more exiting extrusion path
• blockMesh - Improved write-vtk command-line option and simplified edge definition

In Numerics:

• User selectable schemes for high aspect-ratio meshes
• Lagrangian flow has improved particle tracking on moving meshes
• MPPIC sub-models have been transferred to kinematic cloud to improve performance and allow interaction with moving meshes
• Function1 allows setting of a period (more intuitive for slow oscilations)

In Solvers, Physics and Boundary Conditions:

• New vibro-acoustics solver using finite area model to solve a thin vibrating shell
• Improved turbulence treatment on the phase interface to reduce spurious velocities for interFoam and interIcoFoam
• Viscosity models were generalized for easier implementation of new non-newtonian models
• New buoyancyTurbSource implemented to incorporate effects of buoyancy on turbulence in incompressible and compressible flows
• New ACMI scaling option can be used to control coupling and blockage behaviour (simple model of a closing valve)
• Improved outletMappedUniformInlet inlet BC

Many new features and improvements could be found in the post-processing, improved functionality of redistributePar utility.

Compiler configuration and the installation scripts were improved as well.
