Elevator Curtain

[SonDurak]

HELLO THERE; I WANT TO MODEL AN ELEVATOR CURTAIN AS SEEN IN THE ATTACHED PICTURE. BECAUSE THE 25/105 SECTION IN THE X DIRECTION DOES NOT PROVIDE THE RATIO OF SCREEN 1/7 AND THERE IS NO OTHER SCREEN IN THE X DIRECTION, I CHOOSE R COEFFICIENT 8 IN THE X DIRECTION. WHEN I ENTER THE 25/105 SECTION AS A SCREEN AS IN THE 2nd PICTURE, IT GIVES THE ERROR "There are Curtains in the System and the R Coefficient is Greater Than 7". 1. IS IT MORE CORRECT TO MODEL IT AS A COLUMN AS IN THE PICTURE? HOW DO YOU PROPOSE A SOLUTION? THANKS...
