Derived Types

type, public ::  boundary_event_type

Components

Type Visibility Attributes Name Initial
logical, public :: has_event = .false.
real(kind=dp), public :: fraction = 0.0_dp
integer(kind=i32), public :: face_mask = 0_i32
integer(kind=i32), public :: face_bc(6) = -1_i32

Subroutines

public subroutine find_first_boundary_event(cfg, x0, x1, event, status)

閉じたbox内の始点から候補終点へ向かう線分について、最初のbox面交差を返す。

Arguments

Type IntentOptional Attributes Name
class(particle_domain_config), intent(in) :: cfg
real(kind=dp), intent(in) :: x0(3)
real(kind=dp), intent(in) :: x1(3)
type(boundary_event_type), intent(out) :: event
integer(kind=i32), intent(out) :: status

public subroutine apply_escape_reflect_periodic_event(cfg, event, x, v, alive, escaped, status, redistribution_uniform, face_bc)

最初のbox eventへescape/reflect/redistributed-reflect/periodicを軸順序に依存せず適用する。 face_bc を渡すと、box 設定の代わりにその face 別境界条件を event と照合する（外部障壁で一面を反射に 置き換える場合など）。省略時は cfg の bc_low/bc_high。

Arguments

Type IntentOptional Attributes Name
class(particle_domain_config), intent(in) :: cfg
type(boundary_event_type), intent(in) :: event
real(kind=dp), intent(inout) :: x(3)
real(kind=dp), intent(inout) :: v(3)
logical, intent(inout) :: alive
logical, intent(out) :: escaped
integer(kind=i32), intent(out) :: status
real(kind=dp), intent(in), optional :: redistribution_uniform(3)
integer(kind=i32), intent(in), optional :: face_bc(6)

public subroutine apply_ray_box_boundary(cfg, x, dir, alive)

photo raycast の ray が box 面を越えた点に反射・周期境界を適用する。粒子の境界処理は event API （find_first_boundary_event / apply_escape_reflect_periodic_event）が担い、これは ray 専用。 ray は面内再配置の乱数を持たないので、流出面と再配置反射の面では ray を止める（alive=.false.）。 box が無効なら何もせず、幅 0 の軸があれば ray を止める。

Arguments

Type IntentOptional Attributes Name
class(particle_domain_config), intent(in) :: cfg
real(kind=dp), intent(inout) :: x(3)
real(kind=dp), intent(inout) :: dir(3)
logical, intent(inout) :: alive
