Valve length is 1500 mm and from node 80 to node 85 is a ball valve. In real there is a concrete block support to carry weight of valve.
What do you mean? What supports are actually near the valve?
Valve length is 1500 mm and from node 80 to node 85 is a ball valve and rigid. In real there is only a concrete block support to carry weight of valve. But, to me since the valve weight is too much, valve can not move and rotate any direction. So i restrained valve with limit and Rz.
