What does snappyHexMesh do?
In a nutshell, snappyHexMesh is a mesh generator that takes an already existing mesh (usually created with blockMesh) and chisels it into the mesh you want.

Which of the following geometry files are accepted for snappyHexMesh in OpenFOAM?
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 , .
What is mesh check?
checkMesh is a utility which analyzes and evaluates mesh statistics and quality parameters. It can be run anytime by a command: # checkMesh > log.checkMesh & The log contains following information: Statistics about number of points, faces, cells, etc.
What is Salome mesh?

What is topoSet in OpenFOAM?
1 Name. topoSet – Operates on cellSets/faceSets/pointSets through a dictionary.
How does blockMesh work?
The principle behind blockMesh is to decompose the domain geometry into a set of 1 or more three dimensional, hexahedral blocks. Edges of the blocks can be straight lines, arcs or splines. Each block of the geometry is defined by 8 vertices, one at each corner of a hexahedron.

How do you determine good mesh?
Ensuring a well-defined, simplified, clean and critically watertight geometry will often be the difference between a successful high-quality mesh or a poor, illegal, cell-filled one. Geometries should be solid and have no abnormal features such as intersections or sharp outcroppings.
