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
meshinput mesh to create the peripheral area mesh onto
num_sectors_per_sidenumber of azimuthal intervals
peripheral_invervalsnumber of radial intervals of the peripheral region
position_innerkey positions of the inner side of the peripheral region
d_position_outerkey inremental positions of the outer side of the peripheral region
id_shiftshift of subdomain id of the peripheral region
create_inward_interface_boundarieswhether inward interface boundary sidesets are created
create_outward_interface_boundarieswhether outward interface boundary sidesets are created
quad_elem_typetype of quad element to be created
Returns
a mesh with the peripheral region added to a hexagon input mesh
