*CONTROL_ADAPTIVE [1]
-
Global control on all adaptivities (h-adaptivity 2D & shell, r-adaptivity 2D & 3D / shell & solid)

ADPOPT=7 is for 3D r-adaptivity. R-adaptivity often refers to global remeshing to achieve better quality of mesh, while h-adaptivity means refining/coarsening the mesh locally element by element. [2]​ [ex]

-
ADPENE>0 turns on the local refinement in tetrahedron-based remeshing. [3] [ex]
-
*DEFINE_BOX_ADAPTIVE can be used to define multiple boxes in space with different remeshing mesh size, which is a good alternative of ADPENE for mesh refinement and coarsening. [4,5]
​
Card 4

-
IADPFC=1 turns on run-time control of 3D tetrahedron-based r-adaptivity through control files, where adaptive control parameters can be redefined individually for different adaptive parts. The third-party remeshing tool can be used without interrupting the adaptive procedure. [5,6] [ex]
​
*CONSTROL_REMESHING(_EFG) [7]
-
Global control on remeshing and remapping in 3D r-adaptivity.
​
Card 1

-
RMIN & RMAX defines the global minimum and maximum mesh sizes when remeshing in 3D r-adaptivity. [8]
-
CID & SEGANG defines orbital axis and angular mesh size ONLY for 3D orbital r-adaptivity. [9] [ex]

IAT, IAAT and IAT1~3 set up interactive control, which is recommended ONLY for explicit analysis. [11] [ex]
