identify_halo Subroutine

private subroutine identify_halo(haloTreeID, elemPos, haloLevel, levelDesc, tree, updated, nesting, minLevel, stencil)

Map requested halo to a position in my local fluid list or add recursively ghosts until I reach valid fluid elements return type of added element in levelPos(2) Also, non-existing elements are reported as such (levelPos(2))

Arguments

Type IntentOptional Attributes Name
integer(kind=long_k), intent(in) :: haloTreeID

neighboring treeID
integer, intent(out) :: elemPos

type and position in list of found treeID
integer, intent(out) :: haloLevel
type(tem_levelDesc_type), intent(inout) :: levelDesc(minlevel:)
type(treelmesh_type), intent(in) :: tree
logical, intent(out) :: updated
integer, intent(in) :: nesting
integer, intent(in) :: minLevel
type(tem_stencilHeader_type), intent(in) :: stencil
