Creates peripheral area mesh for the patterned hexagon mesh.

Note that the function create the peripheral area for each side of the unit hexagon mesh before stitching. An edge unit hexagon has two sides that need peripheral areas, whereas a corner unit hexagon has three such sides. The positions of the inner and outer boundary nodes are pre-calculated as positions_inner and d_positions_outer; This function performs interpolation to generate the mesh grid.

Parameters

mesh	input mesh to create the peripheral area mesh onto
num_sectors_per_side	number of azimuthal intervals
peripheral_invervals	number of radial intervals of the peripheral region
position_inner	key positions of the inner side of the peripheral region
d_position_outer	key inremental positions of the outer side of the peripheral region
id_shift	shift of subdomain id of the peripheral region
create_inward_interface_boundaries	whether inward interface boundary sidesets are created
create_outward_interface_boundaries	whether outward interface boundary sidesets are created
quad_elem_type	type of quad element to be created

Returns: a mesh with the peripheral region added to a hexagon input mesh
