Models Out Of Use in Evacuation Module

[godisreal]

There are several models in evacuation module which seem out of use for long.
Is there any instruction on how to use them?

1 hawk-dove game
2 group model
3 fall down model

3 Falling Down Model:
I just test the falling down model in a doorway example and it works fine generally.
There are several cases that cause falling down of agents.

(1)

          L_FALLEN_DOWN = .FALSE.
          IF (HR%T_FallenDown < T) THEN
             ! This agent has already fallen down
             L_FALLEN_DOWN = .TRUE.
             GATH = 0.0_EB
             A_WALL = 0.0_EB
          END IF
          HoleFallLoop: DO J = 1, N_HOLES
             EHX => EVAC_HOLES(J)
             IF (EHX%TIME_FALL_DOWN<0.0_EB .OR. EHX%IMESH/=NM) CYCLE HoleFallLoop
             IF (EHX%TIME_FALL_DOWN<T .AND. &
                  EHX%X1<=HR%X .AND. EHX%X2>=HR%X .AND. EHX%Y1<=HR%Y .AND. EHX%Y2>=HR%Y) THEN
                L_FALLEN_DOWN = .TRUE.
                N_DEAD = N_DEAD+1
                HR%T_FallenDown = T
                GATH = 0.0_EB
                A_WALL = 0.0_EB
                EHX%TIME_FALL_DOWN = -1.0_EB
                CYCLE HoleFallLoop
             END IF
          END DO HoleFallLoop
          L_DEAD  = .FALSE.
          IF ( HR%INTDOSE >= 1.0_EB  ) THEN
             L_DEAD = .TRUE.
             ! No random force for a dead person.
             GATH = 0.0_EB
             ! No psychological force terms for a dead person.
             A_WALL = 0.0_EB
             IF (HR%TPRE /= HUGE(HR%TPRE)) THEN
                IF (L_FALLEN_DOWN) N_DEAD = N_DEAD-1 ! Do not duoble count
                N_DEAD = N_DEAD+1
                WRITE (LU_EVACOUT,FMT='(A,I6,A,F8.2,A,I6)') ' EVAC: Agent n:o', &
                     HR%ILABEL, ' dead at ', T, ' s, number of casualties ', N_DEAD
             END IF
             IF (.NOT. L_FALLEN_DOWN) THEN
                HR%T_FallenDown = T
                L_FALLEN_DOWN = .TRUE.
             END IF
             HR%TPRE = HUGE(HR%TPRE)
             HR%TDET = HUGE(HR%TDET)
             HR%COLOR_INDEX = EVAC_AVATAR_NCOLOR
          ELSE
             FED_MAX_ALIVE = MAX(FED_MAX_ALIVE,HR%INTDOSE)
          END IF
          IF (L_FALLEN_DOWN) HR%COLOR_INDEX = EVAC_AVATAR_NCOLOR
          FED_MAX = MAX(FED_MAX,HR%INTDOSE)  ! Dead or alive
          HR_TAU      = HR%TAU
          HR_TAU_INER = HR%TAU_INER
          ! MAX(0,HR%GROUP_ID)  Group index
          IF (MAX(0,HR%GROUP_ID)==0) THEN
             TPRE = HR%TPRE + HR%TDET ! Lonely agent
          ELSE
             TPRE = HR%TDET ! Member of a group
          END IF

                         IF (L_HRE_FALLEN_DOWN) COSPHIFAC = 0.0_EB ! On top of a fallen agent, no social force anymore

                            N_DEAD = N_DEAD+1
                         END IF
                      END IF
