AzimuthalBlockSplitGenerator

This AzimuthalBlockSplitGenerator object takes in a polygon/hexagon concentric circle mesh and renames blocks on a user-defined azimuthal segment / wedge of the mesh.

Overview

The AzimuthalBlockSplitGenerator object is used to modify a mesh generated by either PolygonConcentricCircleMeshGenerator or HexagonConcentricCircleAdaptiveBoundaryMeshGenerator. This object divides each selected radial block in the original mesh into two azimuthal sections and moves the nodes to the exact azimuthal positions.

Multiple radial blocks, which are defined by "old_blocks", can be modified simultaneously. The azimuthal range of the new blocks is defined by "start_angle" and "angle_range" in degrees. The algorithm finds the nodes that have azimuthal angles closest to the given azimuthal range and moves them to the exact azimuthal positions. If the external block (i.e., the block that contains the external boundary of the mesh) is not selected to be modified, the nodes on the external boundary are not altered by this object to facilitate mesh stitching. On the other hand, if the external block is selected, the nodes on the external boundary are moved as well. See Figure 1 for more details.

As moving nodes in the azimuthal direction changes the volumes of the circular blocks, the volume preservation radius correction is made if "preserve_volumes" is set as true.
