Overview

blockMesh is a structured hexahedral mesh generator.

Key features:

• structured hex mesh
• built using blocks
• supports cell size grading
• supports curved block edges

Constraints:

• requires consistent block-to-block connectivity
• ordering of points is important

Well suited to simple geometries that can be described by a few blocks, but challenging to apply to cases with a large number of blocks due to book-keeping requirements, i.e. the need to manage point connectivity and ordering.

Operation

The utility is controlled using a blockMeshDict dictionary, located in the case system directory, split into the following sections:

• points
• edges
• blocks
• patches
