OpenFOAM Dambreak Tutorial. Watch on. If I get a few comments asking for it,. OpenFOAM includes its own generator of volume meshes the snappyHexMesh . Besides the surface mesh of an aircraft this tool needs a suitable background mesh. Background mesh is a simple hexahedral mesh, which fulfills the surrounding domain. It can be for example created by OpenFOAM meshing tools. The settings of the volume mesh generation includes. Environment information OpenFOAM version. The tutorial documentation and source code for examples can be found in the Help/guide/tutorial directory of the CMake source code tree.. Once imported, the mesh consists of actually two separated volumes by the interface_fine and interface_coarse surfaces. The second step is to stitch the meshes by splitting the faces of the two interfaces creating polyhedral cells, so they match each other face to face and node to node: Now the mesh looks something like in Figure 2. The mesh comprises three regions; the background mesh: and two rotors: combined to give: Various concepts are used: Donor cells: cells that provide values; Acceptor cells: these are the cells whose value gets set from interpolation; Hole cells: unreachable/inactive cells; Mesh zone: indicator field to denote potentially overlapping mesh regions.

The blade is subtracted from the rotating region. I am using the automated mesher (ployhedral) meshing both regions simultaneously as there are geometric contacts at the interfaces. The mesh is conformal but I am getting a non conformal mesh after the first step (once the region rotates). Any ideas how to keep the mesh conformal as the region. Create hollow cylinder mesh in OpenFoam (journal bearing simulation) I need to do the journal bearing simulation on OpenFOAM and I have tried several days even setting up the mesh by myself, however, what I get is the full cylinder, instead of the attached picture.
