Partitioned Strong Coupling of Discrete Elements with Large Deformation Structural Finite Elements to Model Impact on Highly Flexible Tension Structures

Algorithm 1

Weak coupling.

(1)	Initialize
(2)	While time < end_time do
(3)	If particle _ near _ wall then
(4)	use predefined time step
(5)	Else
(6)	use increased time step
(7)
(8)	Search nearest neighbours and find contact ⟶ equations (13)–(15)
(9)	Calculate contact forces ⟶ equation (A.5)
(10)	Time integration of DEM part ⟶ equation (16)
(11)	Map forces on from to
(12)	If forcesthen
(13)	Solve structure (FEM)
(14)	Map velocity and displacement on from to
(15)	Update position of to ⟶ equation (1)
(16)	Finalize
