!   This is a shell model of the Eclispe housing P/N 314A120 used
!   on the Pitch Trim Actuator, P/N CU09670019.
!
! Case #
!case=1         ! Two constraint at left end of main housing
!case=2         ! Beam at center extending from left end
!case=3         ! Plate at left end with both nut plates fixed
case=4          ! Plate at left with screw holes and rivet holes

rivet=1         ! Plate with screw holes and rivet holes rotated around screw
                ! 180 degress 0=Don't switch, 1=switch

contact=0       ! Contact elements: 0=Off, 1=On

gload=0         ! 1=Apply accel loading, 0=Link arm force
