Boolean-Based Surface Procedure for the External Heat Transfer Analysis of Dams during Construction

Algorithm 3

Initial detection of the hole surfaces 𝑆₅, transverse joint surfaces 𝑆₆, and rock-exposed surfaces 𝑆_rock.

(1)  𝑆₅=𝑆_𝑎𝑙𝑙−𝑆₁−𝑆₂−𝑆₃−𝑆₄

(2)  for   𝑖=1,2,…,𝑛𝑢𝑚_𝑚𝑜𝑛𝑜−1   do

(3)   𝑆₆ = ((Surface of elements with mono_ID  [lift_ID] = 𝑖) ∧ (those with mono_ID  [lift_ID] =  i + 1)) ∨    𝑆₆

(4)  end  loop   i

(5)  Recognize all external surfaces of elements with mono_ID > 0, and noted them as S_base.

// Searching for only the base elements based on Algorithm 2, that means the foundation faces the dam sits upon will

also be included.

(6)  S_rock    =   𝑆_𝑏𝑎𝑠𝑒−𝑆₁.
