Non-Conforming AMI Patches The arbitrary mesh interface (AMI) was introduced in OpenFOAM v2.1.0 to enable simulation across disconnected, adjacent, mesh domains. It is particularly useful for rotating geometries. Those cases require separate meshes for rotating and/or static regions of geometry, which are coupled at patch boundaries through the cyclicAMI boundary […]

Introduction to foamyHexMesh This version of OpenFOAM includes a new, fully parallelised, meshing tool called foamyHexMesh. It is designed to generate hex-dominant meshes from the same type of surface geometries as used by snappyHexMesh, i.e. triangulated surfaces and in-built analytical surfaces such as spheres, cylinders and planes. The basic principles of […]

Feature Snapping In this release, we have extended existing feature edge handling, reported previously in news and in v2.2.0. Explicit feature snapping uses one or more files containing a description of feature edges in the geometry. snappyHexMesh accepts basic edge mesh file formats, including OpenFOAM’s native .eMesh format, and .obj, […]
